This is a list of seasons completed by the Texas Rangers, originally known as the Washington Senators, professional baseball franchise; they have played in the American League from their inception in 1961. The Rangers have played 61 seasons as a franchise (fifty in Arlington) and have made the postseason nine times.
Formed as the Washington Senators as the replacement team for Washington after the original Senators moved to Minnesota, the Senators played at Griffith Stadium and Robert F. Kennedy Memorial Stadium during their time in Washington, where they had just one winning season (1969) before moving to Arlington, Texas in 1972; the eight consecutive losing seasons from 1962 to 1969 is still the most in franchise history. The team continued to perform poorly, with only one season of over ninety wins and not a single postseason appearance until after the 1994 strike. After the George W. Bush/Edward W. Rose Partnership bought the team in 1989, the Rangers earned three postseason appearances in four years (1996 to 1999). The Rangers again declined to mediocrity under owner Tom Hicks after he bought the team in 1998. A series of questionable deals plagued the team until Hicks put the team into bankruptcy in 2010, at which time an ownership group led by Nolan Ryan and Chuck Greenberg bought the team and the Rangers began the best period of success in franchise history. In total, Texas reached the postseason nine times, won seven division titles along with three American League pennants to reach the World Series thrice (in 2010, 2011 & 2023), winning in 2023 for their first championship in franchise history.
