1964–65 United States network television schedule (late night)

These are the late night schedules on all three networks for each calendar season beginning September 1964. All times are Eastern/Pacific.

1964 marked the debut of Les Crane's short-lived talk show on ABC, the first time since 1955 that any network other than NBC had offered non-news programming in the late-night time slot. Crane's show ended after less than a season.

NET is not included, as member television stations have local flexibility over most of their schedules and broadcast times for network shows may vary, ABC is not included on the weekend schedules (as the network do not offer late night programs of any kind on weekends).

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