Eric Eugene Gregg (May 18, 1951 – June 5, 2006) was an American umpire in Major League Baseball who worked in the National League from 1975 to 1999. He was known for being a pioneering black umpire, for his longtime weight problems, and for his controversial home plate umpiring in Game 5 of the 1997 National League Championship Series—when his generous strike zone helped the Florida Marlins' Liván Hernández strike out 15 Atlanta batters. Throughout his National League career, Gregg wore uniform number 7.
