Sir John Falstaff is a fictional character who appears in three plays by William Shakespeare and is eulogised in a fourth. His significance as a fully developed character is primarily formed in the plays Henry IV, Part 1 and Part 2, where he is a companion to Prince Hal, the future King Henry V of England. Falstaff is also featured as the buffoonish suitor of two married women in The Merry Wives of Windsor. Though primarily a comic figure, he embodies a depth common to Shakespeare's major characters.
