Sir Robert Charles Evans M.D., DSc, (19 October 1918 5 December 1995) was a British mountaineer, surgeon, and educator. He was leader of the 1955 British Kangchenjunga expedition and deputy leader of the 1953 British Mount Everest expedition, both of which were successful.

Kangchenjunga, also spelt Kanchenjunga, is the third highest mountain in the world. It rises with an elevation of 8,586 m (28,169 ft) in a section of the Himalayas called Kangchenjunga Himal delimited in the west by the Tamur River, in the north by the Lhonak Chu and Jongsang La, and in the east by the Teesta River. It lies between India and Nepal, with three of the five peaks, namely Main, Central and South, directly on the border, and the peaks West and Kangbachen in Nepal's Taplejung District.Until 1852, Kangchenjunga was assumed to be the highest mountain in the world, but calculations based on various readings and measurements made by the Great Trigonometrical Survey of India in 1849 concluded that Mount Everest, known as Peak XV at the time, was the highest. Allowing for further verification of all calculations, it was officially announced in 1856 that Kangchenjunga is the third highest mountain in the world.Kangchenjunga was first climbed on 25 May 1955 by Joe Brown and George Band, who were part of the 1955 British Kangchenjunga expedition. They stopped short of the summit following the promise given to the Chogyal that the top of the mountain would remain inviolate.
