Southlake is a city located predominantly in Tarrant County with minor areas extending into Denton County in the U.S. state of Texas. Southlake is a suburb of Dallas/Fort Worth. As of the 2020 census, it had a population of 31,265.

The Southlake area was settled in the 1840s but was not incorporated as Southlake until 1956, four years after the construction of Grapevine Lake was completed. Before incorporation, the settlements of Whites Chapel, Dove, Union Church, and Jellico made up present-day Southlake. The nearby town of Hurst had intended to annex the area that is now Southlake in 1956, but residents voted on Sept. 25, 1956 to form the town of Southlake. Anthony Gail Eubanks was elected the first mayor, and his daughter chose the name Southlake due to its proximity to the newly completed Grapevine Lake. The area remained rural until the completion of the DFW International Airport in the 1970s. Due to the close proximity to the airport, Southlake became a boomburb throughout the 1980s, 1990s and 2000s.

According to the United States Census Bureau, the city has a total area of 22.5 square miles (58 km), of which 21.9 square miles (57 km) is land and 0.6 square miles (1.6 km) (2.45%) is water.
