2002–03 United States network television schedule (daytime)

The 2002–03 daytime network television schedule for the six major English-language commercial broadcast networks in the United States in operation during that television season covers the weekday daytime hours from September 2002 to August 2003. The schedule is followed by a list per network of returning series, new series, and series canceled after the 2001–02 season.

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. Also not included are stations affiliated with Pax TV, as its schedule is composed mainly of syndicated reruns although it also carried some first-run programs.

• New series are highlighted in bold.

• All times correspond to U.S. Eastern and Pacific Time scheduling (except for some live sports or events). Except where affiliates slot certain programs outside their network-dictated timeslots, subtract one hour for Central, Mountain, Alaska, and Hawaii-Aleutian times.
• Local schedules may differ, as affiliates have the option to pre-empt or delay network programs. Such scheduling may be limited to preemptions caused by local or national breaking news or weather coverage (which may force stations to tape delay certain programs in overnight timeslots or defer them to a co-operated or other contracted station in their regular timeslot) and any major sports events scheduled to air in a weekday timeslot (mainly during major holidays). Stations may air shows at other times at their preference.

ABC note: Port Charles aired its final episode on October 3, 2003. ABC returned the 12:30 pm timeslot to its affiliates on October 6. Some affiliates did not air the program at its intended timeslot during its last three months on the air.
