The Texas Rangers are an American professional baseball team based in the Dallas–Fort Worth metroplex. Texas competes 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 Choctaw Stadium from 1994 to 2019. The team's name is shared with the law enforcement agency of the same name.

The franchise was established in 1961, as the Washington Senators, an expansion team awarded to Washington, D.C., after the city's first AL ballclub, the second Washington Senators, moved to Minnesota and became the Twins (the original Washington Senators played primarily in the National League during the 1890s). After the 1971 season, the new Senators moved to Arlington, and debuted as the Rangers the following spring.

The Rangers have made eight appearances in the MLB postseason, seven following division championships in 1996, 1998, 1999, 2010, 2011, 2015, and 2016 and as a wild card team in 2012. In 2010, the Rangers advanced past the division series for the first time, defeating the Tampa Bay Rays. The team then won their first American League pennant after beating the New York Yankees in six games. In the 2010 World Series, the franchise's first, the Rangers fell to the San Francisco Giants in five games. They repeated as American League champions the following year, then lost the 2011 World Series to the St. Louis Cardinals in seven games.

From 1961 through the 2021 season the Rangers' all-time regular season win–loss record is 4,582–5,052 (.476).
