1972–73 United States network television schedule

The following is the 1972–73 network television schedule for the three major English language commercial broadcast networks in the United States. The schedule covers prime-time hours from September 1972 through August 1973. The schedule is followed by a list per network of returning series, new series, and series cancelled after the 1971–72 season. All times are Eastern and Pacific, with certain exceptions, such as Monday Night Football.

New fall series are highlighted in bold.

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

The Prime Time Access Rule, intended to increase diversity in programming and enacted abruptly at the beginning of the previous season was slightly modified, with primetime network programming beginning at 8:00 p.m. Eastern Standard Time from Monday through Saturday and 7:30 p.m. on Sundays, limited to 21 weekly hours. This scheme would remain in place until 1975.

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