Sir Donald Alfred Sinden was a British actor.

Mogambo is a 1953 Technicolor adventure/romantic drama film directed by John Ford and starring Clark Gable, Ava Gardner, and Grace Kelly, and featuring Donald Sinden. Shot on location in Equatorial Africa, with a musical soundtrack consisting entirely of actual African tribal music recorded in the Congo, the film was adapted by John Lee Mahin from the play Red Dust by Wilson Collison. The picture is a remake of Red Dust (1932), which was set in Vietnam and also starred Gable in the same role.
