Janine Wiedel (born 1947) is a documentary photographer and visual anthropologist. She was born in New York City, has been based in the UK since 1970, and lives in London. Since the late 1960s she has been working on projects which have become books and exhibitions. In the early 1970s she spent five years working on a project about Irish Travellers; in the late 1970s two years documenting the industrial heartland of Britain. Wiedel's work is socially minded, exploring themes such as resistance, protest, multiculturalism and counterculture movements.
