Oslo Freedom Forum (OFF) is a series of global conferences run by the New York-based non-profit Human Rights Foundation under the slogan "Challenging Power". OFF was founded in 2009 as a one-time event and has taken place annually ever since. One of the key objectives of the conferences is to bring together notable people, including former heads of state, winners of the Nobel Peace Prize, prisoners of conscience, as well as of other public figures in order to network and exchange ideas about human rights and exposing dictatorships. OFF was founded by human rights activist Thor Halvorssen.
