Robert Douglas "Rob" Gauntlett (10 May 1987 – 9 January 2009) was an English adventurer, explorer and motivational speaker. In 2006 he became the youngest British climber to summit Everest.
Gauntlett grew up in Petworth, West Sussex and was educated at Christ’s Hospital. After graduating, he cycled from Bilbao to Istanbul with a school friend, Richard Lebon.
In 2003, with no climbing experience, Gauntlett and another school friend, James Hooper from Somerset, decided to climb Mount Everest. After training in Scotland, the French Alps, on Spantik in Pakistan and Ama Dablam in Nepal, on 17 May 2006 they reached the summit of Everest, Gauntlett becoming the youngest British climber to do so, a week after his 19th birthday.
Between 8 April 2007 and 9 October 2008 Gauntlett and Hooper made a 180° expedition from North to South Magnetic Poles, using only human and natural power, to help raise awareness of climate change. They travelled by ski, dog sled and sail boat to New York City, by bicycle on to Panama City and then sailed to Guayaquil in Ecuador before resuming on their bicycles for the journey to Punta Arenas, Chile for the very last sea voyage. Having completed the 22,000 mile (35 200 km) trip, the pair sailed 1,800 nautical miles on to Australia.
