Gregory Lamont Vaughn (born July 3, 1965) is an American former baseball left fielder who played for the Milwaukee Brewers (1989-1996), San Diego Padres (1996-1998), Cincinnati Reds (1999), Tampa Bay Devil Rays (2000-2002) and Colorado Rockies (2003) in Major League Baseball (MLB). He was born in Sacramento, California, where he attended Kennedy High School. He then played baseball at the University of Miami. He is the cousin of fellow former major leaguers Mo Vaughn and Jerry Royster.
In 1984 and 1985, Vaughn played collegiate summer baseball for the Cotuit Kettleers of the Cape Cod Baseball League (CCBL). He led the Kettleers to league titles in both seasons, and was league MVP in 1985. Vaughn was inducted into the CCBL Hall of Fame in 2009.
Vaughn was selected by the Brewers in the fourth round (75th pick) of the 1984 amateur draft. A slugger whose batting average dropped below .250 as often as rising above it, he compensated with excellent power. He had three seasons with at least 100 runs batted in, and four with 30 or more home runs - including the 1998 season, when he hit 50 to finish 4th in the major leagues behind Ken Griffey, Jr., Sammy Sosa, and Mark McGwire, who set the home run record that season. In 1999, he became the first player in major league history to be traded after a 50-homer season when the Padres traded him to the Cincinnati Reds. Vaughn's arrival in Cincinnati caused a bit of a controversy with club ownership, as he refused to shave his goatee to comply with the Reds' policy of no facial hair. Fans urged owner Marge Schott to lift the long-standing policy that had been in place since 1967, which she eventually did. On the field, Vaughn hit 45 homers and became the second player in major league history to hit 40 or more homers in consecutive seasons with two different teams (one year after Andrés Galarraga became the first).
Vaughn became eligible for the National Baseball Hall of Fame in 2009. 75% of the vote was necessary for induction, and 5% was necessary to stay on the ballot. He received no votes and dropped off the ballot.
His son, Cory Vaughn, played minor league baseball in the New York Mets organization.
