Dr. Kildare is an NBC medical drama television series which originally ran from September 28, 1961, until August 30, 1966, for a total of 191 episodes over five seasons. Produced by MGM Television, it was based on fictional doctor characters originally created by author Max Brand in the 1930s and previously used by MGM in a popular film series and radio drama. The TV series quickly achieved success and made a star of Richard Chamberlain, who played the title role. Dr. Kildare inspired or influenced many later TV shows dealing with the medical field. Dr. Kildare aired on NBC affiliate stations on Thursday nights at 8:30–9:30 p.m. until September 1965, when the timeslot was changed to Monday and Tuesday nights at 8:30–9:00 p.m. through the end of the show's run.

Dr. James Kildare is a fictional American medical doctor, originally created in the 1930s by the author Frederick Schiller Faust under the pen name Max Brand. Shortly after the character's first appearance in a magazine story, Paramount Pictures used the story and character as the basis for the 1937 film Internes Can't Take Money, starring Joel McCrea as Jimmie Kildare. Metro-Goldwyn-Mayer (MGM) subsequently acquired the rights and featured Kildare as the primary character in a series of American theatrical films in the late 1930s and early 1940s. Several of these films were co-written by Faust, who also continued to write magazine stories and novels about the character until the early 1940s. Kildare was portrayed by Lew Ayres in nine MGM films. Later films set in the same hospital featured Dr. Gillespie. Ayres returned to voice the Kildare character in an early 1950s radio series. The 1961–1966 Dr. Kildare television series made a star of Richard Chamberlain and gave birth to a comic book and comic strip based on the show. A short-lived reboot of the TV series, Young Doctor Kildare, debuted in 1972 and ran for 24 episodes.
