The 2024–25 network late night television schedule for the four major English-language commercial broadcast networks in the United States covers the late night hours from September 2024 to August 2025. The schedule is followed by a list per network of returning series, new series, and series canceled after the 2023–24 television season.
PBS is not included at all, as its member television stations have local flexibility over most of their schedules and broadcast times for network shows may vary. (PBS does offer its member stations packages of "Amanpour & Company" and "BBC World News" to air in late night timeslots Monday–Friday, and optional overnight access to its satellite feed, which rebroadcasts prime time programs shown either the previous evening or earlier in the week). The CW, The CW Plus, and MyNetworkTV are not included as neither programming service offer late night programs of any kind except for overflow of primetime CW Sports programming, nor is Ion Television as its a FAST channel with an OTA feed whose late-night schedule consists of syndicated drama reruns and paid programming.
Fox is not included in the weekday and Sunday schedule, as it only airs late night network programming on Saturdays, and ABC and CBS are not included in the weekend schedule as both networks only air late night network programming on weekdays (except overruns of primetime programming due to sports). NBC is not included on Sundays as it does not offer any network late night programming on Sundays year-round (outside of overruns of its prime time "Sunday Night Football" game telecasts into the late night time period during Fall).
