The Texas Rangers are an American professional baseball team based in the Dallas–Fort Worth metroplex. The Rangers compete in Major League Baseball (MLB) as a member club of the American League (AL) West Division. In 2020, the Rangers moved to the new Globe Life Field in Arlington after having played at Globe Life Park from 1994 to 2019. They are one of two major league clubs based in Texas, alongside the Houston Astros of the same division. The team's name is derived from a historic law enforcement agency.

The Texas Ranger Division, also known as the Texas Rangers and also known as Diablos Tejanos, is an investigative law enforcement agency with statewide jurisdiction in the U.S. state of Texas. It is based in the capital city Austin. In the time since its creation, the Texas Rangers have investigated crimes ranging from murder to political corruption, acted in riot control and as detectives, protected the governor of Texas, tracked down fugitives, served as a security force at important state locations, including the Alamo, and functioned as a paramilitary force at the service of both the Republic (1836–1846) and the State of Texas.
