The Eagle is a 2011 epic historical drama film set in Roman Britain directed by Kevin Macdonald, and starring Channing Tatum, Jamie Bell and Donald Sutherland. Adapted by Jeremy Brock from Rosemary Sutcliff's historical adventure novel The Eagle of the Ninth (1954), the film tells the story of a young Roman officer attempting to recover the lost Roman eagle standard of his father's legion in Caledonia. The story is based on the Ninth Spanish Legion's supposed disappearance in Britain. Historically, the purported disappearance of the Ninth Legion in Northern Britain is a subject of debate.

The film was a UK–US co-production. It was released in the United States on 11 February 2011 and in the United Kingdom on 25 March 2011. The film received mixed reviews from critics and grossed $38 million against its $25 million budget.
