The 1966 Season was the 7th season for the San Diego Chargers as a professional American Football League (AFL) franchise; the team failed to improve on their 9–2–3 record from 1965. In the team's final season at Balboa Stadium, the Chargers went 7–6–1 and finished in third place in the AFL West Division. They would move to San Diego Stadium for the following season. It was the first season to feature an AFL-NFL World Championship Game, now known as the Super Bowl. San Diego began the season among the favorites to represent the AFL in the historic game, but faded after a 4–0 start, winning only three more times in the remaining ten games.
Flanker Lance Alworth was the Chargers' main offensive threat. Catching passes from quarterback John Hadl, he achieved the AFL's triple crown by leading the league in receptions, receiving yards and receiving touchdowns. The Chargers' offense shifted its focus towards the pass, with running back Paul Lowe, the AFL's rushing champion the previous season, seeing far fewer carries in 1966. On defense, the Chargers lost assistant coach Chuck Noll and tackle Ernie Ladd during the offseason, while end Earl Faison left during the regular season. They were strong against the pass, with cornerback Speedy Duncan and safety Kenny Graham making twelve interceptions between them, but became the AFL's worst team against the run.
