Katherine Elaine "Katie" Heenan (born November 26, 1985, in Indianapolis, Indiana)[1] is an American former artistic gymnast.

She sat out the 1999 season due to an injury, but came back in 2000 to place fourth on bars and ninth in the all around at the junior national U.S. Championships.

In 2004, she became the American Classic champion, won gold with her team and on bars at the Pacific Alliance Championships, and competed at the 2004 Olympic Trials.

An injury during the trials prevented her from finishing, but she was asked to become the athlete representative at the final Olympic selection camp.

Heenan received a full scholarship with the Georgia Gym Dogs and throughout her time at the university stood out as a great all rounder.
