Cockrell Hill is a city in Dallas County, Texas, United States. The population was 4,193 at the 2010 census, and 3,815 in 2020. It is completely surrounded by the city of Dallas.

Cockrell Hill was established by the pioneer Brentwood Allen Cockrell and his son, Woodrow. They established the town as a way of making a living, and ran it like a business. The Cockrell place was known to travelers on the stage line that ran from Dallas to Fort Belknap and on to El Paso and the west. The settlement developed as an agricultural crossroads and by the late 1800s had a few scattered homes, a small store, and a school. Water became the overriding issue for the town's continued growth. Frank Jester, a local developer, laid out the plan for the modern community of Cockrell Hill in 1911. A first attempt at incorporation in 1925 proved unsuccessful, and the following year a vote to disincorporate was approved. The second incorporation passed on July 21, 1937, when the population was 459. The town grew to a population of 1,246 in 1941. Many of the new residents worked in war-related industries located in the surrounding areas. In 1952 the population was 2,194, in 1990 it was 3,916, and in 2000 it was 4,445.In May 2006, Councilman Luis D. Carrera defeated C. P. Slayton and John Mendiola defeated Richard Hall and joined Silvia Ulloa, Richard Perez and Sammy Rodriquez to become the first all-Hispanic City Council in North Texas.

On May 30, 1999, Police Officer Tiffany Hickey died six days after she sustained injuries in a motor vehicle collision during pursuit of a suspect. Officer Hickey was the passenger in the patrol car, being driven by her field training officer (FTO), when they attempted to stop a vehicle for speeding and running a red light. Officer Hickey radioed dispatch to notify them of the chase but, due to an antiquated radio system, dispatch never heard the call because another officer was transmitting. Approximately three minutes later the FTO swerved to avoid another vehicle in an intersection and struck a light pole. Officer Hickey remained in serious condition before succumbing to her injuries. Officer Hickey had served with the agency for only 1 month.
