1987–88 United States network television schedule

The 1987–88 network television schedule for the four major English language commercial broadcast networks in the United States covers primetime hours from September 1987 through August 1988. The schedule is followed by a list per network of returning series, new series, and series cancelled after the 1986–87 season.

This is the first fall season in which Fox aired prime-time programming (while it debuted in October 1986, it would only cover late nights until April 1987), making this the first full season since 1958-59 in which a fourth commercial television network (NTA) was broadcasting. Fox would air only two days a week (Saturdays and Sundays) until the spring of 1989.

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

New series are highlighted in bold. Series ending their network runs are highlighted in italics.

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

From February 13 to 28, 1988, all of ABC's primetime programming was preempted in favor of coverage of the 1988 Winter Olympics in Calgary.

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