Dr. Kildare was a radio show produced at WMGM New York, based on the popular Dr. Kildare movies from the late 1930s and early 1940s. The show starred Lew Ayres as the young, idealistic Dr. James Kildare and Lionel Barrymore as the seasoned diagnostician, Dr. Leonard Gillespie. The series followed their work at Blair General Hospital, focusing on Kildare's dedication to his patients while navigating the challenges of hospital administration and the eccentric characters that populated the hospital. The show's dramatic tone emphasized the cutting-edge medical techniques employed by the characters to save their patients, while the actors' strong performances provided a solid basis for engaging storytelling.

Dr. Kildare was created as a radio adaptation after its successful run as a film series, which was in turn inspired by the original character of Dr. James Kildare from author Frederick Schiller Faust's pulp-crime fiction stories. The radio show aired from the late 1940s to the early 1950s and featured several notable actors such as Stacy Harris, Isabel Jewell, Jay Novello, George Ellis, Paul Frees, Raymond Burr, and Jack Webb. In addition to the films and radio show, Dr. Kildare had several other adaptations, including a 1961–1966 TV series starring Richard Chamberlain, a comic book, a comic strip, and a 1972–1973 syndicated TV series called "Young Dr. Kildare."
