Sir John Laurence "Jack" Longland (26 June 1905 – 29 November 1993) was an educator, mountain climber, and broadcaster.
After a brilliant student career Longland became a don at Durham University in the 1930s. He formed a lifelong concern for the welfare of unemployed people, and after a time working in community service he moved to become an educational administrator, retiring in 1970. Among his achievements was the establishment of White Hall in Derbyshire, the country's first local authority Outdoor Pursuits Centre for young people.
