Michael Graeme Groom (born 1959) is an Australian mountaineer. In 1995, Groom became the fourth person ever to reach the summits of the five highest peaks in the world (Makalu, Lhotse, Kangchenjunga, K2 and Everest) without using bottled oxygen. In 1987 he lost the front third of his feet to frostbite after descending from the summit of Kangchenjunga. Despite this, he managed to summit Mount Everest in 1993 and again in 1996. He has also completed the Seven Summits (highest mountains on each of the seven continents). Groom acted as a guide for Adventure Consultants during the 1996 Mount Everest disaster, which he survived and subsequently described in his 1997 autobiography. In the 2015 film Everest, Groom was portrayed by actor Tom Wright. In the 2000 Australia Day Honours Groom was awarded the Medal of the Order of Australia (OAM) for "service to mountaineering".
