Michael Henry Flanders (1 March 1922 – 14 April 1975) was an English actor, broadcaster, writer and performer of comic songs. He is best known for his stage partnership with Donald Swann.

As a young man Flanders seemed to be heading for a successful acting career. However, he contracted polio in 1943 while serving in the Royal Navy Volunteer Reserve and for the rest of his life was reliant on a wheelchair. He made a career as a prolific broadcaster on the radio and later on television. Moreover, he together with his old school friend, the composer Donald Swann, wrote successful songs in the late 1940s to the early and mid-1950s for revues in the West End of London. In 1956 they themselves performed some of these songs, along with new songs, in a two-man revue, At the Drop of a Hat. This show, and its successor, At the Drop of Another Hat, ran with occasional short breaks from 1956 to 1967 and played in theatres throughout the British Isles, the US, Australia and elsewhere.

During and after the stage partnership with Swann, Flanders pursued a many-faceted career, performing on stage, screen, radio, concert platforms and recordings. He wrote opera librettos, a children's book, a volume of poetry and the words of Captain Noah and His Floating Zoo, a cantata about Noah's Ark.
