1970 San Diego Chargers season

The  San Diego Chargers season was the franchise's eleventh overall season and first season in the National Football League (NFL). As a result of the NFL-AFL Merger, where the league was broken into two conferences, each member of the American Football League was moved into the American Football Conference.

San Diego's 5–6–3 record was the first of seven consecutive losing seasons for the franchise. The 1970 Chargers are the last NFL team to record three ties in a single season, a record which will likely stand, as since the NFL adopted overtime for regular season games in 1974 no team has recorded more than one tie in a season.
