Christopher Geis was a rock climber who competed on the second season of American Ninja Warrior.

In qualifying, his run was digested, but it was shown that he cleared the course in 1:03.6 minutes, guaranteeing 28th place and a spot in the finals. In the semi-finals, his run was digested again, but it was shown that he surprisingly went out on the Jumping Bars, after failing to make the transition to the final bar. He attempted to make a one-handed save, but could not stick it and lost his grip, placing 24th overall and failing to move on to Boot Camp.
