The 1991 San Diego Chargers season was the franchise's 22nd season in the National Football League (NFL), the 32nd overall and the third and final season under head coach Dan Henning. The team failed to improve on their 6–10 record in 1990, losing eight of their first nine games and finishing at 4-12, their fourth consecutive losing season. Henning, together with his entire coaching staff, was fired by general manager Bobby Beathard the day after the season ended.
