Lawman is an American Western television series originally telecast on ABC from 1958 to 1962, starring John Russell as Marshal Dan Troop and Peter Brown as Deputy Marshal Johnny McKay. The series was set in Laramie, Wyoming, during 1879 and the 1880s. Warner Bros. already had several Western series on the air at the time.

Television Westerns are programs with settings in the later half of the 19th century in the American Old West, Western Canada and Mexico during the period from about 1860 to the end of the so-called "Indian Wars". More recent entries in the Western genre have used the neo-Western subgenre, placing events in the modern day, or the space Western subgenre but still draw inspiration from the outlaw attitudes prevalent in traditional Western productions.
