Markham is a CBS drama television series starring Ray Milland, which aired during the 1958-1959 and 1959-1960 seasons following Gunsmoke on Saturday nights, under the sponsorship of the Joseph Schlitz Brewing Company. Milland played private investigator and attorney Roy Markham. In that Markham had been a successful lawyer, he had the leisure to take detective cases based on his own interest.

Prior to Markham, Milland played the lead role from 1953-1954 in a CBS sitcom, Meet Mr. McNutley, the story of a college professor at fictitious Lynnhaven College, an all-girls institution. For the second season, 1954–1955, the program was renamed The Ray Milland Show.
