George Herbert Leigh-Mallory (18 June 1886 – 8 or 9 June 1924) was an English mountaineer who participated in the first three British Mount Everest expeditions from the early to mid-1920s. He and his climbing partner Andrew "Sandy" Irvine were reported to be last seen ascending near Everest's summit during the 1924 expedition, sparking debate as to whether they reached it before they died.
