The Adventures of Philip Marlowe was a radio series featuring Raymond Chandler's private eye, Philip Marlowe. Robert C. Reinehr and Jon D. Swartz, in their book, The A to Z of Old Time Radio, noted that the program differed from most others in its genre: "It was a more hard-boiled program than many of the other private detective shows of the time, containing few quips or quaint characters."

In 1948, the series moved to CBS, where it was called The Adventure of Philip Marlowe, with Gerald Mohr playing Marlowe. This series also began with an adaptation of "Red Wind", using a script different from the NBC adaptation. By 1949, it had the largest audience in radio. The CBS version ran for 114 episodes. That series ran 26 September 1948 – 29 September 1950..
