The 2007–08 network television schedule for the six major English language commercial broadcast networks in the United States covers the prime time hours from September 2007 through August 2008. The schedule is followed by a list per network of returning series, new series, and series canceled after the 2006–07 season. The schedule was affected by the 2007–08 Writers Guild of America strike (which began on November 5 and ended on February 12). After that, the next disruption to the networks' primetime schedules would not occur until the 2020–21 season, whose network schedules were affected by the suspension of film and television productions as a result of the COVID-19 pandemic.

NBC was the first to announce its fall schedule on May 14, 2007,^[1] followed by ABC on May 15,^[2] CBS on May 16,^[3] Fox and The CW on May 17,^[4][5] and MyNetworkTV on August 24, 2007.^[6]

This was the first TV season where Nielsen Media Research kept track of DVR ratings (live plus same day; C3; live plus 7)^[7]

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

Each of the 30 highest-rated shows released in May 2008 is listed with its rank and rating as determined by Nielsen Media Research.^[8]

New series are highlighted in bold.

Repeat airings or same-day rebroadcasts are indicated by (R).

All times are U.S. Eastern and Pacific Time (except for some live sports or events). Subtract one hour for Central, Mountain, Alaska and Hawaii-Aleutian times.

All sporting events air live in all time zones in U.S. Eastern time, with local and/or late-night programming (including Fox affiliates during the 10 p.m. ET/PT hour) by affiliates after game completion.

All NBC programming from August 8, 2008, to August 24, 2008, was pre-empted for coverage of the 2008 Summer Olympics in Beijing.^[9]

On November 5, the Writers Guild of America went on strike. During the strike, production on scripted television series across all of the major television networks was suspended. The writers' strike forced the networks to postpone the start of the fall 2007 schedule later than usual; rather than the traditional late-September/early-October start, new and returning series had their premieres delayed until late October and into November. The Writers Guild of America strike ended on February 12. The 2007–08 television season was thus the first of three television seasons to have its start delayed due to issues outside of the control of the major networks; the other instances were the 1988–89 season (due to the 1988 Writers Guild of America strike) and the 2001–02 season (due to the networks' news coverage of the September 11 attacks). The next major disruption to the primetime television schedules of the major television networks would not occur until the 2020–21 season (due to a suspension of television productions as a result of the COVID-19 pandemic). The third major disruption to the primetime television schedules of the major television networks was the 2023 Writers Guild of America strike, and the 2023 SAG-AFTRA strike.
