George Henry Lowe III (born August 16, 1944) is an American rock climber and alpinist, noted for his history of alpine-style mountaineering on difficult and infrequently repeated routes and his development of traditional climbing routes in the Western United States. He pioneered winter ascents in the North American Rockies along with cousins Jeff Lowe (climber), Mike Lowe, and Greg Lowe. He is also known for his technically difficult ascents of mixed climbing faces in the Himalayas including the unclimbed North Ridge of Latok I (within 200m of the summit) and the first ascent of the East Face of Mount Everest (Kangshung Face), where the Lowe Buttress bears his name.
