The Adventures of Ellery Queen was a radio detective program in the United States. Several iterations of the program appeared on different networks, with the first one broadcast on CBS on June 18, 1939, and the last on ABC on May 27, 1948.

Ellery Queen is a pseudonym created in 1928 by the American detective fiction writers Frederic Dannay (1905–1982) and Manfred Bennington Lee (1905–1971). It is also the name of their main fictional detective, a mystery writer in New York City who helps his police inspector father solve baffling murder cases. From 1929 to 1971, Dannay and Lee wrote around forty novels and short story collections in which Ellery Queen appears as a character.
