Ellery Queen was an American television mystery series that ran for one season from 1975 to 1976 on NBC. It starred Jim Hutton (father of Timothy) as Ellery Queen, and David Wayne as his father, Inspector Richard Queen. One of several television adaptations of the Ellery Queen mystery novels (see also The Adventures of Ellery Queen), the series was created by the successful writing and producing team of Richard Levinson and William Link, who also created such mystery fare as Mannix, Columbo and Murder, She Wrote.

The series premiered on March 23, 1975 with the made-for-TV movie Ellery Queen (also titled Too Many Suspects), adapted from the book The Fourth Side of the Triangle. A total of 22 episodes followed in the show's one and only season, the last of which aired April 4, 1976.

Set in the post-WWII 1940s, the show closely followed the format of the Ellery Queen mystery novels which carefully laid out the clues before the reader/audience and invited them to attempt to solve the mystery before Ellery Queen presented the solution. In the early Queen books, just prior to the presentation of the solution to the mystery, a "Challenge To The Reader" was issued, in which the suspects and clues were reviewed and the reader challenged to guess the solution to the crime. In the show this tradition was preserved by having Ellery Queen break the fourth wall and speak directly to the viewer prior to the commercial break that led into the final act. The final act always employed the time-honored detective cliché of calling all of the suspects together with Ellery Queen presenting the solution to the group.

In addition to the lead actors Jim Hutton and David Wayne, the series also featured regulars Tom Reese as Inspector Queen's right-hand-man Sergeant Velie, John Hillerman as radio detective Simon Brimmer, and Ken Swofford as reporter Frank Flannigan.

The third TV adaptation of the adventures of super-sleuth Ellery Queen, this time set during the 1940s. Queen was a mystery writer who assisted his father, a detective with the New York Police Department, in solving murders. Sgt. Velie was Inspector Queen's assistant and Simon Brimmer a rival detective. Queen's methods were arcane and intellectual rather than action oriented, and he always astounded his father by arriving at a correct solution by purely deductive reasoning. In this version, just before he revealed his solution to the crime, Queen always turned to the camera and asked the TV audience if they had figured out the identity of the killer yet -- they had all the clues -- because he was about to reveal the correct killer as we met the entire slew of suspects in one room for the ending.
