The 1966 San Francisco 49ers season was the franchise's 17th season in the National Football League, their 21st overall, and their fourth under head coach Jack Christiansen.
The 49ers attempted to improve on their 7âÂÂ6âÂÂ1 record from the previous year and make the playoffs for the first time in 8 years. However, the 49ers faltered, starting their season 0âÂÂ2âÂÂ1. Despite winning their next 3 games, they split their next 8 games and tied 1 game to finish the season 6âÂÂ6âÂÂ2, and they missed the playoffs for the ninth straight year.
Note that sack totals from 1960 to 1981 are considered unofficial by the NFL.
