Andrew Kirkpatrick is a British mountaineer, author, motivational speaker and monologist. He is best known as a big wall climber, having scaled Yosemite's El Capitan over 30 times, including five solo ascents, and two one-day ascents, as well as climbing in Patagonia, Alaska, Antarctica and the Alps. He has also crossed Greenland by ski. In 2014 he guided Alex Jones up Moonlight Buttress, Zion National Park, raising £1.9 million for Sport Relief.

Big wall climbing is a form of rock climbing that takes place on long multi-pitch routes that normally require a full day, if not several days, to ascend. In addition, big wall routes are typically sustained and exposed, where the climbers remain suspended from the rock face, even sleeping hanging from the face, with limited options to sit down or escape unless they abseil back down the whole route. It is therefore a physically and mentally demanding form of climbing.
