L'Homme de la Mancha () is Jacques Brel's twelfth studio album. Released in 1968, it is the cast recording of the French adaptation of The Man of la Mancha by Mitch Leigh and Joe Darion. Brel adapted the book, translated the lyrics, directed the production, and played the role of Don Quixote. This was the only time he ever adapted songs by other writers or appeared in a stage musical. Joan Diener, who played Dulcinea in the original 1965 production, reprised the part in this production. The album was reissued on 23 September 2003 as part of the 16-CD box set Boîte àbonbons by Barclay (980 817-5).
