Honey West is a ground-breaking American crime drama television series that aired on ABC from September 17, 1965, to April 8, 1966, as an entry in the 1965–1966 television season. Based upon a series of novels that had launched in 1957, the series starred Anne Francis as female private detective Honey West and John Ericson as her partner Sam Bolt. The popular series was historic in that it marked the first time a woman played the lead character in a network TV series with her character's name as the title.
