Jeffrey Crompton, often stylized as "Geoff" or "Geff" (July 4, 1955 – January 7, 2002), was an American professional basketball player.

A 6'11 Parade All-American center from Walter M. Williams High School in Burlington, North Carolina, Crompton attended the University of North Carolina to play for future Hall of Fame coach Dean Smith in 1973.

Crompton played very sparingly for the Tar Heels, appearing in a total of 9 games from 1973 to 1977 due to academic and weight issues.

The highlight of his career may have been being named CBA Most Valuable Player in 1984 as a member of the Puerto Rico Coquis.

After his professional career ended, Crompton moved to Tallahassee, Florida, and managed a restaurant.
