Cedric Henning Belfrage (8 November 1904 – 21 June 1990) was an English film critic, journalist, writer, and political activist.
He is best remembered as a co-founder of the radical US-weekly newspaper the National Guardian.
Later Belfrage was referenced as a Soviet agent in the US intelligence Venona project, although it appears that he had been working for British Security Co-ordination as a double-agent.
