The 2005 San Francisco 49ers season was the 60th year for the team overall, and their 56th season in the NFL. They improved their two-win 2004 season by two games. Former head coach Dennis Erickson had been fired just after the end of the 2004 season, and Mike Nolan (son of former Niners head coach Dick Nolan) took the helm. San Francisco's 1,898 team passing yards in 2005 were the lowest such total in the decade of the 2000s.
