Vista (/ˈvɪstə/; Spanish for "view") is a city in San Diego County, California. It is a medium-sized city within the San Diego-Carlsbad, CA metropolitan statistical area. As of the 2020 Census, Vista had a population of 98,381. Current data estimates a 2023 population of 99,835. Vista's sphere of influence also includes portions of unincorporated San Diego County to the north and east, with a county island in the central west. Located just 7 mi (11 km) inland from the Pacific Ocean, it has a Mediterranean climate.

Much of Vista's current territory was once part the Mexican land grants Rancho Buena Vista and Rancho Guajome. A post office was established on October 9, 1882, and Vista was incorporated as a city on January 28, 1963, later becoming a charter city on June 13, 2007.

The Vista area was originally inhabited by the Luiseño Indians, who established a village in today's Vista called Tovalum.

The prosperity of the mission-era declined by the 1830s with the independence of Mexico from Spain. The Mexican government began to grant land ownerships to a variety of people, thus beginning the Rancho era of California. Three ranchos were granted in the Vista area: Rancho Guajome, Rancho Buena Vista, and Agua Hedionda Y los Manos.

In the 1850s the ranchos began to fade due to changing political conditions and the scarcity of water. A growing number of settlers came to the area after California became a state in 1850 and began to create smaller agricultural holdings. One settler in the Vista area, John A. Frazier, applied to open the first post office and after several attempts to name the city (Frazier and Buena Vista were already taken), Frazier finally chose the name "Vista"; the post office was opened in 1882.

In 1870, Bernard Delpy arrived from France to build what eventually became known as "Delpy Corners" at the intersection of today's East Vista Way and Foothill Drive. His nephew, Jules Jacques Delpy, joined him in 1879 and together they planted several hundred acres of grapes. In 1886, they built the first successful winery in the country. The winery was shut down by the Prohibition era.

Inhibited by the lack of water, Vista grew slowly through the early 1910s to less than 1,000 people. With a 1923, however, the Vista Irrigation District had the necessary funding to construct a new water supply from Lake Henshaw. Agriculture began to flourish in the area, including citrus fruits, tomatoes, celery, and most prominently avocados. Vista became home to multiple avocado packing facilities, and by the late 1940s was promoted as "the avocado capital of the world" The rise in agriculture led in turn to further commercial development.

Following World War II, agriculture declined with an influx of population and housing. The City of Vista was incorporated on January 23, 1963. The frequent housing booms of the 1970s through early 2000s greatly increased the population of Vista, and the city limits have grown as well. Many light manufacturing businesses moved into Vista beginning in the 1980s, and with the founding of several breweries in the 21st century Vista has become a significant element in the San Diego craft beer phenomenon.

Since the 1990s, the downtown area has received about $12 million in investments from Vista for improvements. The City of Vista released a plan in 2015 for the further development of downtown, aiming to make it the main commercial, social, and cultural hub in Vista. In 2020, Vista finished the Paseo Santa Fe corridor project, which transformed almost a mile of Santa Fe Avenue into a pedestrian-friendly street with a number of restaurants and housing complexes.

According to the United States Census Bureau, the city has a total area of 18.7 square miles (48 km2) of land. Like much of the California coastal area, the landscape is marked by hills and valleys. In undeveloped areas, the natural vegetation types includes chaparral brushland, oak-sycamore woodland, riparian (stream) woodland, and oak-grass savanna.

Vista has a semi-arid climate (Köppen: BSk) bordering on a Mediterranean climate (Csa). Extremes of temperature uncommon. Frost is quite rare in winter, and snowfall almost unknown; the last significant snowfall in Vista was in 1967. Most of the annual rainfall of 13.24 inches (336 mm) falls between November and April. The mild weather led to the city's promotional motto "America's Climatic Wonderland", which was in use for many years.

The 2022 American Community Survey 1-Year Estimates reported that within Vista city, whites and Hispanics were the most numerous race/ethnic groups. The top ancestries were German, English, and Irish. Whites made up 75.5% of the population, while the remainder was largely Hispanic or Latino at 14.9%.

Approximately 9.1% of the population was below the poverty line, an improvement over both the national and California state averages. The poverty rate was highest among single parent households with young children (greater than 20%), and lowest among married couple households with young children (less than 5%). The majority of households were married couple families, and the majority of homes were single-family detached houses. More residents owned their homes than rented.
