The 1991 World Series pitted the Minnesota Twins (95–67) of the American League against the Atlanta Braves (94–68) of the National League; Minnesota won in seven games.ESPN selected it as the "Greatest of All Time" in their "World Series 100th Anniversary" countdown, with five of its games being decided by a single run, four games decided in the final at-bat and three games going into extra innings.

In addition to the suspense of the outcome of many of its games, the Series had other highlights. For example, the series-deciding seventh game was a scoreless tie (0–0) through the regular nine innings, and went into extra innings; Minnesota won the seventh game by a score of 1-0 in the 10th inning, with their starting pitcher, Jack Morris, pitching all ten innings (Morris was named Most Valuable Player for the Series).

With 69 innings in total, the 1991 World Series holds the record for longest seven-game World Series ever (some of the early years had nine-game Series, extending longer).

The 1991 World Series was notable for several grueling contests, with five of its games being decided by one run and three games in extra innings (including the third game, a twelve-inning marathon which saw Twins manager Tom Kelly run out of hitters).

The ceremonial first pitch of the World Series prior to Game 1 was thrown by retired AL umpire Steve Palermo. Palermo had been forced into early retirement when he was seriously injured by gunshot while coming to the aid of a robbery victim in Dallas on July 7, 1991. After the pitch, the Series umpires jogged to the mound to exchange well wishes.

The Twins started their ace, Minnesota native Jack Morris, while the Braves countered with Charlie Leibrandt. Both pitchers had pitched on World Series teams, with Morris winning a World Series ring with the 1984 Detroit Tigers and Leibrandt winning one with the 1985 Kansas City Royals. Leibrandt was the only Braves starter who had World Series experience.
