The 2001–2002 United States network television schedule is for United States broadcast television on all six commercial television networks for the fall season beginning in September 2001. All times are Eastern and Pacific, with certain exceptions, such as Monday Night Football.

New fall series are highlighted in bold.

NOTE: The September 11 attacks hindered the ability to start airing shows in a timely manner. Although many series began their seasons in September and October as regularly scheduled, the television season officially did not begin until the month of November. From February 8 to 24, 2002, all of NBC's primetime programming was preempted in favor of coverage of the 2002 Winter Olympics in Salt Lake City.

Each of the 30 highest-rated shows is listed with its rank and rating as determined by Nielsen Media Research.^[1]

PBS is not included; member stations have local flexibility over most of their schedules and broadcast times for network shows may vary.

NOTE: FOX aired 2 episodes of The Chamber in mid-January 2002. During the fall, Futurama and King of the Hill were preempted by overruns of NFL games. On The WB, Lost in the USA was supposed to air at 7-8, but it was cancelled due to 9/11 problems.

Note: On ABC, The Runner was supposed to start when Monday Night Football concludes, but it was cancelled due to production problems.

Note: Buffy the Vampire Slayer and Roswell moved to UPN from The WB this season.

NOTES: 1. When ABC announced their 2001 Fall Schedule, originally the plan was for The Job to air after The Drew Carey Show starting in mid-September and NYPD Blue would air in the 10pm ET timeslot after 20/20 Downtown returned to Friday nights in late December.^[2] However, after the terrorist attacks on September 11th, 2001, ABC decided to not air The Job until mid-season because the show was set in New York City. In October, when the sitcom Bob Patterson was not doing well in the ratings on Tuesday nights, they moved the show to the Wednesday 9:30pm ET timeslot and put NYPD Blue in the Tuesday 9pm ET timeslot.

2. That '80s Show premiered midseason on January 23 on FOX in the 8:00pm ET timeslot.

NOTE: FOX aired The Chamber on January 25th, 2002 after two preview airings on past Sunday nights. The show was cancelled after its Friday night airing.
