1966–67 United States network television schedule (late night)

These are the late-night schedules for all three networks for the 1966–67 season. All times are Eastern and Pacific.

The United Network launched in spring 1967 with its lone program, The Las Vegas Show. The show and network ended after one month and 23 episodes, most of which aired on CBS stations in areas where the United Network did not own a station.

NET is not included, as member television stations had local flexibility over most of their schedules, and broadcast times for network shows might have varied. ABC and CBS are not included on the weekend schedules because those networks did not offer late-night programs of any kind on the weekend.

Talk/Variety shows are highlighted in yellow, Local News & Programs are highlighted in white.
