Harold Andrew Raeburn (21 July 1865 – 21 December 1926) was a Scottish mountaineer. He was one of the most prominent British mountaineers of his era with several first ascents. In the late 19th and early 20th centuries he took part in numerous ascents in Norway, contributing to the popularization of Norwegian mountaineering among the international mountaineering community. Some of his regular mountaineering partners in Norway were William Cecil Slingsby, Howard Priestman and Norwegians Kristian Tandberg and George Paus. He was mountaineering leader on the initial 1921 British Mount Everest reconnaissance expedition.
