Laredo is an American Western television series that aired on NBC from 1965–67, starring Neville Brand, William Smith, Peter Brown, and Philip Carey as Texas Rangers. It is set on the Mexican border around Laredo in Webb County in South Texas. The program presented 56 episodes in color. It was produced by Universal Television. The series has a comedic element, but like another NBC series that premiered in 1965, The Wackiest Ship in the Army, it was an hour in length, had no laugh track, and characters were not infrequently killed in it, thus going against three unofficial rules for sitcoms at the time.

The pilot episode of Laredo aired in 1965 on NBC's The Virginian under the title "We've Lost a Train". In 1969, the pilot was released theatrically under the title Backtrack. Three episodes from the series were edited into the 1968 feature film Three Guns for Texas.
