The following is the 1971–72 network television schedule for the three major English language commercial broadcast networks in the United States. The schedule covers primetime hours from September 1971 through August 1972. The schedule is followed by a list per network of returning series, new series, and series cancelled after the 1970–71 season. All times are Eastern and Pacific, with certain exceptions, such as Monday Night Football. This season would be the first time the prime time schedule would be shortened to three hours (with the exception of Sunday and Tuesday), giving the 7:30 p.m. slot back to local stations, as implemented in the Prime Time Access Rule.

New fall series are highlighted in bold.
