The Tenth Man was a short-lived radio series created by the National Mental Health Foundation and aired on NBC from October 17, 1947 to January 16, 1948. It featured 13 episodes that focused on various aspects of mental health, from children's issues to those affecting the elderly. Jackson Beck was the announcer, and Ralph Bellamy served as the narrator. The show aimed to raise awareness about the fact that one in ten people would need psychiatric care at some point in their lives.

From stories of activist Dorothea Dix's efforts to improve the treatment of the mentally ill to explorations of depression, loneliness, and social phobias, The Tenth Man provided an educational and altruistic platform to discuss mental health issues. Despite its ambitious mission, the series remains lesser-known in the realm of old-time radio shows.
