Dr. James Kildare was a fictional character, the primary character in a series of American theatrical films in the late 1930s and early 1940s, an early 1950s radio series, a 1960s television series of the same name and a comic book based on the tv show. The character was invented by the western fiction author, Frederick Schiller Faust.

The character began the film series as a medical intern; after becoming a doctor he was mentored by an older physician, Dr. Leonard Gillespie. After the first ten films, the series eliminated the character of Kildare and focused instead on Gillespie.
