Henry F. Potter (commonly referred to as Mr. Potter or just Potter) is a fictional banker portrayed by veteran actor Lionel Barrymore in the 1946 Frank Capra film It's a Wonderful Life.

Both Dan Duryea and Charles Bickford were considered for the role of "Potter".Although Lionel Barrymore won an Academy Award for Best Actor in A Free Soul in 1931, in the 1940s he was well-known as the voice of Ebenezer Scrooge in CBS radio dramatizations of A Christmas Carol, and is now best remembered for his role as Henry Potter. A wheelchair-user due to a hip injury and severe arthritis, Barrymore played Potter as confined to a wheelchair due to polio. His wheelchair is pushed in all scenes by a wordless assistant (played by Frank Hagney).
