Alan Leroy Hairston (born December 11, 1945) is an American former professional basketball player and a college and high school head coach.

His high school coaching career has garnered him multiple league, district and state championships, as well as numerous individual awards.

He also successfully coached the Kent-Meridian (Kent, WA) and Seattle O'Dea High School boys basketball programs to post-season appearances.

In assuming the O'Dea post, he took over for the late Phil Lumpkin – also a former NBA basketball player and prep coaching star.

There, the Washington Huskies lost to a Jim Calhoun coached University of Connecticut team on a buzzer-beater by future NBA star Richard "Rip" Hamilton.
