The Texas Rangers 1981 season involved the Rangers finishing second in the American League West with a record of 57 wins and 48 losses. The season was suspended for 50 days due to the infamous 1981 players strike and the league chose as its playoff teams, the division winners from the first and second halves of the season, respectively.

The 1981 Major League Baseball season culminated with the Los Angeles Dodgers defeating the New York Yankees in the World Series, capturing the franchise's fifth World Series title. The season had a players' strike, which lasted from June 12 to July 31, and split the season into two halves. Teams that won their division in each half of the season advanced to the playoffs. This was the first split season in American League history, and second for the National League, which had played a split season in 1892.
