Douglas Osborne McClure was an American actor whose career in film and television extended from the 1950s to the 1990s. He is best known for his role as the cowboy Trampas during the entire run from 1962 to 1971 of the series The Virginian and mayor turned police chief Kyle Applegate on Out of This World. From 1961-1963, he was married to actress BarBara Luna.

The Virginian is an American Western television series starring James Drury in the title role, along with Doug McClure, Lee J. Cobb, and others. It originally aired on NBC from 1962 to 1971, for a total of 249 episodes. Drury had played the same role in 1958 in an unsuccessful pilot that became an episode of the NBC summer series Decision. Filmed in color, The Virginian became television's first 90-minute Western series. Cobb left the series after four seasons, and was replaced over the years by mature character actors John Dehner, Charles Bickford, John McIntire, and Stewart Granger, all portraying different characters. It was set before Wyoming became a state in 1890, as mentioned several times as Wyoming Territory, although other references set it later, around 1898.
