Banyon was a detective series aired in the United States by NBC as part of its 1972-73 lineup, though a stand-alone two-hour TV movie first aired in March 1971. The show was a Quinn Martin Production (in association with Warner Brothers Television), the first-ever show Martin made for the NBC network.

Banyon was a period drama set in the late 1930s in Los Angeles. It revolved around the life of private investigator Miles C. Banyon (Robert Forster), a tough-but-honest detective who would take on essentially any case for $ 20/day. Located in the same complex (the famed Bradbury Building) as Banyon's office was the secretarial school operated by Peggy Revere (Joan Blondell). By an agreement between Banyon and Revere, part of the training provided to these young women was a turn serving as Banyon's secretary; this gave him the advantage of not having to provide a salary for a secretary but meant that he never had the same one long enough for her to become a truly knowledgable or reliable assistant. Besides Revere, the other ongoing female character was Banyon's girlfriend Abby Graham (Julie Gregg), a nightclub singer who was constantly trying to encourage him to "settle down" and marry her, but to no avail during the brief run of this series. Banyon's police connection in the LAPD was the cynical Lieutenant Pete McNeil (Richard Jaeckel). The series was a Warner Brothers production.

Banyon was unable to find an adequate audience and lost in the Nielsen ratings to Love, American Style on ABC and movies on CBS and was cancelled at midseason.

Miles Banyon was a tough but honest private detective operating out of Los Angeles during the '30s. For $20 a day plus expenses, Banyon would take almost any case, ranging from missing persons to theft to murder. Since his office was located in the same building as Peggy Revere's secretarial school, Banyon found himself with a different pretty receptionist almost every week. His police contact was Sgt. McNeil. Written by Marty McKee
