These are the late-night schedules for the three U.S. television networks during the 1974–75 season. All times are Eastern and Pacific.
PBS is not included, as member television stations had local flexibility with 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.
