Justin is a city in Denton County, Texas, United States. The population was 3,246 at the 2010 census.
It is also an outer ring suburb of Fort Worth.
In 1848, approximately 70 followers of the French utopian socialist Étienne Cabet arrived in what is now Justin to found an Icarian community. The attempt failed.
Contrary to popular belief, the town is not named after or related to the Justin Boot Company. In January 1887 the community petitioned postal authorities for a post office to be named Justin, in honor of Justin Sherman, a chief engineer with the Santa Fe Railroad.
Justin once was a center of salvage companies, which buy property involved in fires and tornadoes and sell it for discounted prices. In the late 1970s Western wear became very popular, and the Wallace family's salvage operations began to focus on Western wear. The other two major salvage businesses closed, and the salvage industry disappeared.
The Texas Motor Speedway had a Justin mailing address until July 9, 2005. Because it is physically located in the city of Fort Worth, the United States Postal Service changed the mailing address to Fort Worth, Texas.
WFAA-TV, Channel 8, has operated a 750 kilowatt Doppler weather radar out of Justin since January 25, 1995.
One of the FBI Ten Most Wanted Fugitives, Yaser Abdel Said, was captured in Justin on August 26, 2020.
According to the United States Census Bureau, the city has a total area of 2.4 square miles (6.2 km2), all of it land.
Some areas along FM 156 and Hwy 114 use the Justin ZIP code (76247) even though the land is within the City of Fort Worth.
