Petra Klingler (born February 14, 1992) is a Swiss competition rock climber.
Known as a versatile climber, she competes in bouldering and speed, lead, and ice climbing.
It is historically rare for a climber to compete in so many different disciplines, especially ice climbing, although the combined format of the Tokyo Olympics has made it more common.
Klingler was encouraged by her former coach to try ice climbing for fun, and as a way to build mental discipline.
