The 2008–09 daytime network television schedule for the four major English-language commercial broadcast networks in the United States covers the weekday and weekend afternoon hours from September 2008 to August 2009.
The schedule is followed by a list per network of returning and cancelled shows from the 2007–08 season.
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.
Also not included are MyNetworkTV (as the programming service doesn't offer daytime programs of any kind), and Ion Television (as its schedule is composed mainly of syndicated reruns).
Fox is not included on the weekday schedule: Fox only airs daytime programming (in the form of sports on weekend afternoons).
