Monica Jackson (16 September 1920 - 7 April 2020) was a Scottish climber and part of the first non-male expedition to scale the Jugal Himal in the Himalayas. In 1955, she climbed the Jugal Himal with Elizabeth (Betty) Stark and Evelyn McNicol. They managed to get to the previously unmapped Phurbal Chyachumbu glacier and made it to the 22,000 ft peak on the frontier of Nepal and Tibet. They named it Gyalgen Peak, after their lead Sherpa. Jackson wrote the book Tents in the Clouds: the first women's Himalayan expedition in 1957 about the adventure.
