Brathay Trust is a youth charity with its head office and residential centre based at Brathay in Cumbria, England. Founded in 1946 by Francis C. Scott, the charity is based at the Brathay Hall and estate near the town of Ambleside. The organisation's main focus is on training and developing general skills for youth, including Lake District-based outdoor education and experiential learning, but also organises people and organisation development courses for adults. In 2007, the trust began holding the Brathay Windermere Marathon, a now annual charity marathon.
