The following is the 1975–76 network television schedule for the three major English language commercial broadcast networks in the United States. The schedule covers primetime hours from September 1975 through August 1976. The schedule is followed by a list per network of returning series, new series, and series cancelled after the 1974–75 season. All times are Eastern and Pacific, with certain exceptions, such as Monday Night Football. This was the first season since 1971 in which a four-hour Sunday night schedule was implemented. This was also the first season for the 22-hour weekly prime-time schedule (four hours on Sunday, three hours each on Monday through Saturday). It remains in effect to this day. New fall series are highlighted in bold. Series ending their original runs are in italics.
