Anonymous is a 2011 period drama film directed by Roland Emmerich and written by John Orloff. The film is a fictionalized version of the life of Edward de Vere, 17th Earl of Oxford, an Elizabethan courtier, playwright, poet and patron of the arts, and suggests he was the actual author of William Shakespeare's plays. It stars Rhys Ifans as de Vere and Vanessa Redgrave as Queen Elizabeth I of England.

The film premiered at the Toronto International Film Festival on September 11, 2011. Produced by Centropolis Entertainment and Studio Babelsberg and distributed by Columbia Pictures, Anonymous was released on October 28, 2011 in the United States, Canada and the United Kingdom, expanding to theatres around the world in the following weeks. The film was a box office flop and received mixed reviews, with critics praising its performances and visual achievements, but criticising the film's time-jumping format, factual errors, and promotion of the Oxfordian theory of Shakespeare authorship.
