Gregory Carpenter Gagne (born November 12, 1961 in Fall River, MA) is a former shortstop who played 10 seasons for the Minnesota Twins from 1983 to 1992, including both of the Twins' World Series championship teams in 1987 and 1991. He was considered one of the American League's best defensive shortstops during his time with Minnesota. He also played for the Royals and the Dodgers.

Greg was drafted by the New York Yankees in the fifth round of the 1979 Major League Baseball Draft, and debuted with the Twins in 1983.

On October 4, 1986 during a Twins' home game at the Hubert H. Humphrey Metrodome, Greg tied a modern-era major league record by hitting two inside-the-park home runs against the Chicago White Sox. Only 18 players in major league history have performed this feat, with Gagne being only the second since 1930.

Greg was a fixture of the Twins drive to their second World Series appearance, and first World Series title, following the 1987 season. During the Twins march to their second World Series crown in four years, he hit a game-winning, three-run homer in Game One of the 1991 World Series (see 1:38:56). Overall, Gagne slugged five doubles and 4 home runs, along with knocking in 10 runs and scoring 12 times in postseason play.

Gagne retired from baseball following the end of the 1997 season. After retiring, he was the head baseball coach at Bishop Feehan High School.

Gagne continues to be revered by Twins fans. He was a guest at the Metrodome farewell ceremony. On February 8, 2010, Gagne was elected to the Twins Hall of Fame and was inducted at Target Field on September 4, 2010.
