Events
January-March
- March 11 - Johnny Mize and Rube Foster are elected to the Hall of Fame by the Special Veterans Committee. Mize hit .312 with 359 home runs in 15 seasons for the Cardinals and New York Giants, while Foster was a star pitcher, manager and pioneer of the Negro Leagues during the first quarter of the 20th century.
April-June
- May 15 - Len Barker of the Cleveland Indians pitches a perfect game against the Toronto Blue Jays, 3-0, at Cleveland Municipal Stadium. He struck out 11, all swinging, after the third inning and never had a 3-ball count on any batter on a misty, rain-soaked night where only 7,290 fans took in the game. Current Indians broadcaster Rick Manning caught the 27th out of the night on a fly ball to center field.
- June 12 - After meeting with major league owners for most of the previous day, players' union chief Marvin Miller announces, "We have accomplished nothing. The strike is on," thus beginning the longest labor action to date in baseball history. By the time the season resumes on August 10, 706 games (38 percent of the season schedule) will have been canceled.
July-September
- September 6 - Despite having won the first-half American League East title, New York Yankees manager Gene Michael is replaced by Bob Lemon, who managed the club in 1978-79. The Yankees are under .500 in the second half of the season.
October-December
- October 3 - Bob Horner hits two home runs and scores the winning run to give the Atlanta Braves a 4–3 win over the Cincinnati Reds, and give the Houston Astros the second-half title in the NL West division. Cincinnati, which lost the first-half title to the Dodgers by one-half game, will finish with the best overall record (66-42) in the major leagues, but will not make the playoffs.
- October 3 - The Milwaukee Brewers (playing since 1970) and Montréal Expos (since 1969) clinch their first-ever postseason appearances. Milwaukee beats Detroit 2–1 to wrap up the second-half title in the AL East division, while Montréal edges the Mets 5–4 to win the NL East division's second playoff spot.
- October 5 - The Kansas City Royals shut out Cleveland 9–0 in the first game of a scheduled doubleheader to clinch the second-half title in the AL West division. The second game is canceled as irrelevant.
- October 28 - Pedro Guerrero drives in five runs, and pitcher Burt Hooton and the Los Angeles Dodgers beat the New York Yankees 9–2 to win the 1981 World Series in six games. In a remarkable postseason, the Dodgers rallied from a 2-0 deficit against the Astros in the division series, they rallied from a 2 games to 1 deficit against the Expos in the National League Championship series, and they rallied from a 2-0 deficit against the Yankees in the World Series. Guerrero, Ron Cey and Steve Yeager are named co-MVPs.
