Tyler is a city in and the county seat of Smith County, Texas, United States. As of 2020, the population is 105,995. Tyler was the 38th most populous city in Texas (as well as the most populous in Northeast Texas) and 289th in the United States. It is the principal city of the Tyler metropolitan statistical area, which is the 198th most populous metropolitan area in the U.S. and 16th in Texas after Waco and the College Station–Bryan areas, with a population of 233,479 in 2020. The city is named for John Tyler, the tenth President of the United States.

In 1985, the international Adopt-a-Highway movement began in Tyler. After appeals from local Texas Department of Transportation officials, the local Civitan International chapter adopted a two-mile (three kilometer) stretch of U.S. Route 69 to maintain. Drivers and other motorists traveling on this segment of U.S. 69 (between Tyler and nearby Lindale) will see brown road signs that read "First Adopt-A-Highway in the World".

Tyler is known as the "Rose Capital of America" (also the "Rose City" and the "Rose Capital of the World"), a nickname it earned from a long history of rose production, cultivation, and processing. It is home to the largest rose garden in the United States, a 14-acre public garden complex that has over 38,000 rose bushes of at least 500 different varieties. The Tyler Rose Garden Center is also home to the annual Texas Rose Festival which attracts thousands of tourists each October.

As Northeast Texas and Smith County's major economic, educational, financial, medical and cultural hub, Tyler is host to more than 20,000 higher-education students; the University of Texas at Tyler; a university health science center; and regional hospital systems. It is the headquarters for Brookshire Grocery Company and many other large employers. Tyler is also home to the Caldwell Zoo and Broadway Square Mall, and the seat of Roman Catholic Diocese of Tyler and its Cathedral of the Immaculate Conception.

Legal recognition of Tyler was initiated by an act of the state legislature on April 11, 1846. The Texas government created Smith County and authorized a county seat.

The first plat designated a 28-block town site centered by a main square within a 100-acre (40 ha; 0.16 sq mi) tract acquired by Smith County on 6 February 1847. The new town was named for President John Tyler, who advocated for the annexation of Texas by the United States. A log building on the square's north side served as a courthouse and public meeting hall until a brick courthouse displaced it in 1852. The City of Tyler was incorporated on January 29, 1850. Early religious and social institutions included the First Baptist Church and a Methodist church, a Masonic lodge and an Odd Fellows lodge, and Tyler's first newspaper.

Though Tyler's early economy from 1847–1873 was based on agriculture, it was also well-diversified during this period. Logging was a second major industry, while complementary manufacturing included metalworking, milling wood, and leather tanning. As the seat of Smith County, the town also benefited from government activity. The local agricultural economy relied on slave labor before the Civil War. In 1860, the population of enslaved people in Smith County was 4,982, the 4th most in east Texas.

By 1860, Tyler held over 1,000 enslaved persons, which represented 35 percent of the town's population. There was strong support for secession and the Confederacy within Tyler, as a high percentage of its residents voted for secession and many of its men joined the Confederate Army. The town was secure enough for the Confederate States of America to establish the largest ordinance plant in Texas. In 1870, Bonner and Williams established Tyler's first bank. When both the Texas and Pacific Railroad and the International Railroad (Texas) originally eschewed routes through Tyler, townspeople financed the Tyler Tap Railroad to link the town to the national rail grid. Ironically, before that 21-mile line to Big Sandy, Texas was completed in 1877, Tyler had already gotten its desired rail connection when the International–Great Northern Railroad built into town in 1874. Regardless, the Tyler Tap became the seed for the 725-mile-long Texas and St. Louis Railway, which in turn formed the core of the later St. Louis Southwestern Railway, commonly known as the Cotton Belt.

Toward the end of the nineteenth century, fruit orchards emerged as an important business in the regional economy. Eighty percent of the county's agricultural revenue derived from cotton as it persisted as the dominant crop in the first decades of the twentieth century. Peaches were the principal fruit crop as the county fruit tree inventory surpassed one million by 1900. Disease struck the peach trees, though, and local farmers moved toward growing roses by the 1920s. Twenty years later, most of the U.S. rose supply originated in the Tyler area.

On October 29, 1895, an African American suspect named Robert Henry Hillard was burned at the stake in the Smith County Courthouse Square for the alleged murder of a nineteen-year-old white woman. Denied a trial and due process, Hillard was taken from law enforcement personnel by a white mob. Hillard's executioners were never punished. Later, two entrepreneurs combined photographs from the actual lynching with others staged with actors and sold the 16-image production as a stereographic set. One of the original sets sits in the United States Library of Congress.

In 1912, Dan Davis, an African-American man suspected of attacking a sixteen-year-old white girl named Carrie Johnson, was burned at the stake in the Smith County Courthouse Square.

In 1971, the University of Texas system established the University of Texas at Tyler and Broadway Square Mall opened in 1975. By 1980, the population grew to 70,508 and the Roman Catholic Diocese of Tyler and East Texas Islamic Society were established in the following years.

During the 2010 East Texas church burnings, two Tyler churches were destroyed, and historic preservation city planning began in 2016 as the population increased and the city continued development.
