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) of Major League Baseball (MLB).

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[2] that had been in place since 1967, which she eventually did.

Earning back-to-back 4th place finishes in NL MVP voting, 1998-99 would be Vaughn's career peak.

His son, Cory Vaughn, played minor league baseball in the New York Mets organization.
