Koestler Arts (formerly The Koestler Trust) is a charity which helps ex-offenders, secure patients and detainees in the UK to express themselves creatively. It promotes the arts in prisons, secure hospitals, immigration centres and in the community, encouraging creativity and the acquisition of new skills as a means to rehabilitation. The Koestler awards were founded in 1962 and the organisation became a charitable trust in 1969 following a bequest from the British-Hungarian author, Arthur Koestler.
