The 2022–23 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 2022 to August 2023.
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.)
Fox is not included in the weekday 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).
Please note that the schedules for the networks are affected by the 2023 Hollywood labor disputes.
