乔治·约翰特·里·马洛里（George Herbert Leigh Mallory，1886年6月18日－1924年6月8日或9日）是英国探险家，在尝试攀登珠穆朗玛峰途中丧生。

他在被问及为何想要攀登珠穆朗玛峰时回答说，“因为它就在那儿。”（"Because it's there."），成为人们至今经常引用的名言。

马洛里曾就读于****和剑桥大学，与著名经济学家约翰·梅纳德·凯恩斯曾经是同学与好友。1922年马洛里首次从北坡挑战珠穆朗玛峰没有成功，2年后与队友安德鲁·欧文（Andrew Irving）再度尝试登顶，最终一去不复返，而有关两人死前到底是否曾经登顶的争议也成为登山历史上著名的“马欧之谜”。如果能够证明两人生前确曾登顶，则将改变珠峰的历史，这次攀登也将成为人类历史上首次征服珠穆朗玛峰。

George Herbert Leigh Mallory (18 June 1886 – 8 or 9 June 1924) was an English mountaineer who took part in the first three British expeditions to Mount Everest in the early 1920s.

During the 1924 British Mount Everest expedition, Mallory and his climbing partner Andrew "Sandy" Irvine both disappeared on the North-East ridge during their attempt to make the first ascent of the world's highest mountain. The pair were last seen when they were about 800 vertical feet (245 m) from the summit.
