The 2018–19 daytime network television schedule for four of the five major English-language commercial broadcast networks in the United States covers the daytime hours from September 2018 to August 2019.
Affiliates fill time periods not occupied by network programs with local or syndicated programming.
PBS – which offers daytime programming through a children's program block, PBS Kids – is not included, as its member television stations have local flexibility over most of their schedules and broadcast times for network shows may vary.
Fox does not offer daytime network programming nor network news on weekdays; as such, schedules are only included for Saturdays and Sundays.
Also not included are MyNetworkTV (as the programming service also does not offer daytime programs of any kind), and Ion Television (as its schedule is composed mainly of syndicated reruns).
