Hemet is a city in the San Jacinto Valley in Riverside County, California. It covers a total area of 29.3 square miles (76 km2), about half of the valley, which it shares with the neighboring city of San Jacinto. The population was 89,833 at the 2020 census. It borders San Jacinto to the north, East Hemet to the east, Polly Butte and Diamond Valley Lake to the south, and Green Acres and Juniper Springs to the west.

The founding of Hemet, initially called South San Jacinto, predates the formation of Riverside County. This area was then still part of San Diego County. The formation of Lake Hemet helped the city to grow and stimulated agriculture in the area.

The city is known for being the home of The Ramona Pageant, California's official outdoor play, set in the Spanish colonial era. Started in 1923, the play is one of the longest-running outdoor plays in the United States.

Hemet has been named a Tree City USA for 20 years by the Arbor Day Foundation for its dedication to the local forest. The city is home to the Hemet Valley Medical Center, a 320-bed general hospital.

This had long been the territory of the indigenous Soboba people and Cahuilla tribe prior to Spanish colonization. During the early 19th century, Mission San Luis Rey used the land for cattle ranching. They named the area with the settler name Rancho San Jacinto.

Hemet was named by the land development company that founded the town, The Lake Hemet Land Company. The company drew its name from Hemet Valley, now called Garner Valley, located in the San Jacinto Mountains. Initially, the company referred to the area as South San Jacinto, but changed the name to Hemet when the land company filed a plat map on November 11, 1893.

Following Mexico gaining independence from Spain, in 1842, settler José Antonio Estudillo received the Rancho San Jacinto Viejo Mexican land grant.

In 1848, the United States annexed the California territory after defeating Mexico in the Mexican–American War. In 1887, during the first major Southern California land boom, Anglo-Americans W.F. Whittier and E.L. Mayberry founded the Lake Hemet Water Company, and the Lake Hemet Land Company, for speculative development. They had plans to dam the San Jacinto River to provide irrigation water to the valley. They named the town Hemet in November 1893.

In 1895, they completed Hemet Dam as a private project on the San Jacinto River, creating Lake Hemet and providing a reliable water supply to the San Jacinto Valley. This water system, for irrigation in an arid region, was integral to the valley's development as an agricultural area.

By 1894, settlers had established a newspaper, the Hemet News, and "several general stores", the largest being Heffelfinger & Co, which occupied an entire block. Other businesses included "a drug store, an excellent barber shop, two blacksmith shops, harness shop, shoe repairing houses, two real estate offices and two lumber yards." "The most pretentious building" was the two-story Hotel Mayberry, "supplied with all the modern conveniences usually found in first-class hostelries, including stationary water, baths, etc., and a complete electric light system, the power for which is furnished by the company's private plant." Also noted was the Hemet flour mill, owned by John McCool and built at a cost of $20,000. It was the only such mill in this area, and was housed in a brick building. It could produce 50 barrels of flour per day.

Hemet was incorporated in January 1910. Of 177 residents, 130 voted to incorporate, with 33 against. Those who voted against incorporation were landowners who feared increased taxation. The incorporation helped to serve the growing city, which was outgrowing its current infrastructure.

With a railroad spur running from Riverside, the city became a trading center for San Jacinto Valley agriculture; commodity crops included citrus, apricots, peaches, olives, and walnuts. The Agricultural District Farmer's Fair of Riverside County began here in 1936 as the Hemet Turkey Show. It was relocated to Perris.

During World War II, the city hosted the Ryan School of Aeronautics, which trained about 6,000 fliers for the Army Air Force between 1940 and 1944. The site of the flight school was redeveloped as Hemet-Ryan Airport. In 1950, Hemet was home to 10,000 people, joining Corona and Riverside as the three largest cities in Riverside County.

Hemet was racially discriminatory. Numerous African Americans migrated to California during and after World War II in the Great Migration from such Deep South states as Mississippi, Louisiana, and Texas. Hemet was a sundown town, prohibiting African Americans from living there or even staying overnight.

In the 1960s, large-scale residential development began, mostly in the form of mobile home parks and retirement communities. Hemet was known as a working-class retirement area. In the 1980s, former ranchland was developed in subdivisions of single-family homes. "Big-box" retail followed the increase in population. After a roughly decade-long lull in development following the major economic downturn of the early 1990s, housing starts in the city skyrocketed in the early 21st century. The area's affordability, its proximity to employment centers such as Corona, Riverside and San Bernardino, and its relatively rural character made it an attractive location for working-class families priced out of other areas of Southern California.

Hemet is in the San Jacinto Valley of western Riverside County, south of San Jacinto. The valley, surrounded by the Santa Rosa Hills and San Jacinto Mountains, is mostly dry land, except for Diamond Valley Lake to the south. According to the United States Census Bureau, the city has a total area of 29.28 square miles (76 km2), all land.

Hemet is 80 miles (130 km) southeast of Downtown Los Angeles.

Hemet has a semi-arid climate (Köppen climate classification: BSh) with mild winters and very hot, very dry summers.

According to the City of Hemet's 2023 Annual Comprehensive Financial Report, the ten largest employers in the city are:

The City of Hemet has two museums and an outdoor amphitheater. The Hemet Museum is located at the intersection of State Street and Florida Avenue in downtown. It is a museum of local history, and features photographs of old Hemet, historic photographs from the Ramona Pageant, as well as Cahuilla cultural belongings such as baskets and agriculture displays. Hemet is also home of the Western Science Center, located in the southern part of the city at the intersection of Domenigoni Parkway and Searl Parkway. It features exhibits of Ice Age mammals, including 'Max', the largest mastodon found in the Western United States, and 'Xena', a Columbian mammoth. Along with the two museums, science center and theater, close to Hemet there sits an outdoor amphitheater, the privately owned Ramona Bowl is a natural amphitheater located nearby in the Riverside county foothills. It is known for producing the play, Ramona.

The city of Hemet is expanding upon its entertainment venues. The three largest venues are the Ramona Bowl, an outdoor amphitheater, a Regal Cinemas and the Historic Hemet Theatre, built in 1921. A development being planned for the area is a downtown transit village, with the center of it being a Metrolink station. It will be north of the downtown core, and will consist of residences, shops, and parks. The station itself could feature a railroad museum, a heritage trail, and a farmer's market and market hall.

The Historic Hemet Theater was once the oldest continually run single-screen theater in the nation. However, the theater was forced to close down in January 2010 due to water damage from a fire that destroyed adjacent store fronts. The musty smell forced the theater to stay closed for a year, which created financial struggles. As of 2011[update], the foundation was incorporated as a non-profit 501(c)3 for the purpose of supporting community projects. In July 2013, the Historic Hemet Theater Foundation negotiated a five-year lease/option to purchase the theater. As of 2016, the Foundation had restored the Theater back to operation and was in the process of raising funds in order to purchase and restore the Hemet Historical Treasure.

Scenes for The Fast and the Furious (2001) were filmed on Domenigoni Parkway. The grandstands and track at the Hemet Stock Farm were a filming location for the movie Seabiscuit (2003). The movie Hemet, or the Landlady Don't Drink Tea (2023) was filmed in San Diego County, but the location setting is in Hemet.

In addition to Diamond Valley Lake, Hemet has six large parks as part of the Valley-Wide Recreation and Parks District, which also includes the cities of San Jacinto and Menifee as well as a number of unincorporated areas.

Brubaker park contains one large children's play area, one half basketball court, eleven baseball/softball fields, fitness trails, two picnic areas, and one portable restroom.

The Diamond Valley Lake Community Park opened in September 2009. The 85-acre (34 ha) park, part of the eastern recreation area of Diamond Valley Lake, has eight lighted ball fields, three soccer fields, four pickleball courts, four restrooms, and three picnic areas. The park is also adjacent to the Diamond Valley Aquatic Center.

Gibbel Park contains a large children's play area, one ball field, a half basketball court, restrooms, two lighted tennis courts, a lawn bowling green, horseshoe pits, picnic areas, and a large turf area for passive uses. The park also features a memorial of military branches of the United States. In October 2023, a skate park was opened. In 2024, pickleball courts were added. It has an area of 11 acres (45,000 m2), and was established in 1970.

Dedicated to Mary Henley, who was born in Hemet and served as Hemet City Clerk from October 1951 to March 1975. The park contains two playground areas, a half basketball court, picnic tables, shade structures, restrooms and a large turf area. There is a marked walking path/sidewalk of 0.75 miles (1.2 km) around the perimeter of the park. It has an area of 16 acres (65,000 m2), and was established in 1993. A fitness court was opened in October 2022.

Dedicated to James Simpson, Hemet City Council from 1947 to 48, and mayor from 1950 to 1966, Simpson Park is a wilderness park located in the Santa Rosa Hills southeast of Hemet with sheltered picnic area and tables, barbecues, restrooms, and hiking trails. At an elevation of 2,500 feet (760 m), it provides an expansive view of the San Jacinto Valley, as well as the nearby cities and towns of Winchester, Menifee, and Temecula, and it has an area of 438 acres (1.8 km2).

Weston Park was established in 1921 and was dedicated to John B. Weston, who was president of the board of trustees from 1914 to 1920. It contains shuffleboard courts, restrooms, a playground, a basketball court, and a turf area for passive uses and games. It is located in the downtown area west of Santa Fe Street, and has an area of 4 acres (20,000 m2).

The educational services of the majority of the city are under the Hemet Unified School District. It covers most of Hemet, and parts of San Jacinto, and Valle Vista, with a student population of over 20,000 students. There are also HUSD member schools in the rural communities of Anza, Idyllwild and Winchester.

As of January 2010, the school district was facing having to possibly go far out of budget to fix the Historic Hemet Elementary school, due to the fact that it was built on top of a swamp and has been sinking deeper every year. The main building was built in 1927, and is one of the few historic landmarks left in Hemet. The other choice would be to demolish the school and build a new one in its place. The State of California will pay for 50% of either project, but the already cash-strapped district may run into trouble if the repairing of the school goes over budget. A new building could cost $20 million, with an extra $3 million to have it built in the original architectural style of the old building.

A portion of Hemet is in the San Jacinto Unified School District.

Two California State Highways cross the city. California State Route 74 runs along most of Florida Avenue, the main corridor of east and west transportation in Hemet, and California State Route 79 also follows Florida Avenue for a few miles in the city. Highway 79 is slated for re-alignment when the Mid County Parkway project begins. Streets in Hemet are arranged mostly in a standard grid. Almost all major streets that go east–west are avenues, and almost all streets going north–south are streets. Exceptions are Sanderson Avenue, Lyon Avenue, Palm Avenue and Cawston Avenue. Major streets in Hemet are Florida Avenue, Sanderson Avenue, San Jacinto Street, Stetson Avenue, and State Street.

The City of Hemet public library was created in 1906. Members of the Women's Club opened a reading room at the corner of Harvard Street and Florida Avenue.

In 1910, citizens of the newly formed city voted for its own library, and the city took over the operation of the facility built in 1906. Shortly after, the reading room became too small for the growing community, and groups and citizens lobbied for a newer, larger facility to house the growing collection of books. A woman of the community named Mrs. E.A. Davis was the one who wrote to Andrew Carnegie seeking funds to help build a new library. The city received $7,500 to fund part of the construction, and Mr. and Mrs. St. John donated land to the city to build the new Carnegie Library. The new library was finished in 1913, and served the city for 52 years. The building was declared unsafe by the Fire Marshall and razed in 1969, and the new C.B. Covell Memorial Library was built. This building however, also became too small for the city.

The library moved again in 2003, to its current facility, relocated for the first time since 1913. The new facility is now located at 300 E. Latham Avenue, just blocks from its former location. The new building is two stories tall, and contains 52,000 square feet (4,800 m2). It was designed by John Loomis of 30th Street Architects at a cost of over $15 million.
