Dr. Kildare was a radio show produced for syndication in 1949 at WMGM, New York. Based on the popular Dr. Kildare movies from the late 1930s and early 1940s, the show starred Lew Ayres as young and idealistic Dr. James Kildare and Lionel Barrymore as the crusty yet loveable diagnostician Dr. Leonard Gillespie. Set in Blair General Hospital in New York, the show followed Kildare's battles with hospital administration and the various challenges encountered by the medical staff.

The series was marked by its engaging and solid stories, especially when the characters ventured outside the hospital environment. The writing and directing were handled on a freelance basis, with notable actors such as Stacy Harris, Raymond Burr, and Jack Webb contributing to the show.

The radio show featured cutting-edge medical techniques and storylines that were up to date for its time. The series enjoyed popularity with audiences but ultimately stopped producing new episodes after 1951. Nevertheless, rebroadcasts of old episodes continued in syndication for several more years.
