Under the Red Robe is a 1923 American silent historical drama film directed by Alan Crosland based upon the Stanley Weyman novel Under the Red Robe. The film marks the last motion picture appearance by stage actor Robert B. Mantell who plays Cardinal Richelieu and the only silent screen performance of opera singer John Charles Thomas.
The novel was also filmed in 1915 (by Wilfred Noy), and again in the sound era in 1937 (by Victor Sjöström).
The film survives complete at the George Eastman House. A Samuel Goldwyn release, it was donated by MGM.
