Robert Alan Lock (born May 22, 1966) is an American former professional basketball player. Lock was born and raised in Reedley, California and played collegiate ball with the University of Kentucky (1984–1988) where he was a solid contributor off the bench and increased his stats every year he played. He entered the 1988 NBA draft and was picked 51st in the third round by the Los Angeles Clippers; however, Lock accepted an offer to play in Italy instead. He did eventually return to play for just 20 games with Clippers during the latter part of the 1988-89 NBA season.
