The Heart of a Man is a 1959 British drama film directed by Herbert Wilcox and starring Frankie Vaughan, Anne Heywood and Tony Britton. A millionaire in disguise gives a young man money to help him pursue his singing career.

Featured songs by Vaughan include "The Heart of a Man", "Sometime, Somewhere" and "Walking Tall".

Sailor Frankie Martin is offered a thousand pounds by an eccentric tramp if he can earn a hundred pounds in a week by honest means. Frankie tries his hand as a boxer, a bouncer and a commissionaire, and finally finds success as a singer. He also falls for the charms of night club chanteuse Julie, and this leads to further success when he wins a recording contract.

The movie was the fourth collaboration between Frankie Vaughan and Anna Neagle, following These Dangerous Years, Wonderful Things! and The Lady Is a Square although those had been made for Associated British and this one was made for Rank. The movie featured two Rank contract stars, Anne Heywood and Tony Britton.

Filming started 19 January 1959 under the title Give Me the Moonlight. "We aren't fighting television," said Herbert Wilcox. "We are fighting hooligans in the cinema audience. You can't play a sensitive love scene today because it gets a laugh. But we're beating them. I turn a love scene to comedy and get in with the laugh first."

Wilcox also said "The important thing is that it is upbeat. We insist on that in everything that we do. Whether the story is in a Liverpool gambling den or a Park Lane penthouse. Downbeat subjects encourage the hooligans. They sneer at the situations. They guy the love scenes. They throw things. People say television is killing the cinema. They forget hooliganism. Together they are a frightening team."

The Rank Organisation issued a single sung by Anne Heywood in the film on its record label.

Mike Pratt and Lionel Bart wrote songs for the film.
