The Adventures of Ellery Queen is a radio detective program that features an amateur mystery writer in New York City, who helps his police inspector father to solve baffling murder cases. Adapted from the novels and short stories written by Frederic Dannay and Manfred Bennington Lee, the show's format invites a panel of armchair detectives to try to solve each case during its broadcast. A "Challenge to the Reader" is inserted right before the solution, declaring that the reader has seen all the same clues Ellery Queen has, and only one solution is possible. The show's tone is less "hardboiled" than other pulp detective stories of the time, embracing the intellectual aspect of solving mysteries.

The Adventures of Ellery Queen aired from June 18, 1939, to May 27, 1948, and appeared on different networks, including CBS, NBC, and ABC. Over its run, it featured a total of over 750 guest panelists. The radio show was expanded into the Ellery Queen's Minute Mysteries in the mid-1960s, primarily working as "filler" spots with 70-second mysteries that included all the clues and a local sponsor message.
