Colleyville is a city in northeastern Tarrant County, Texas, United States, centrally located in the Dallas–Fort Worth metroplex.

A wealthy suburb of the Dallas/Fort Worth area, Colleyville was originally a small farm town in the 19th century.

Emerging from a number of small, rural settlements along the Cotton Belt Route, Colleyville was originally known as Bransford when Dr. Lilburn Howard Colley settled there in 1880.

In 1914, when Walter G. Couch opened a grocery store near Dr. Colley's home, the community was renamed Colleyville in his honor.

Colleyville, located in the conservative stronghold of northeastern Tarrant County, votes overwhelmingly Republican[16] in all elections, as do most suburban cities in the Dallas–Fort Worth metroplex.

Northwestern Colleyville lies inside Keller Independent School District, which maintains one campus within the city.

American Airlines, headquartered nearby in Fort Worth, maintains its largest hub at DFW.
