1980 San Francisco 49ers season

The 1980 San Francisco 49ers season was the franchise's 31st season in the National Football League and their 35th overall. This was the second year with the team for both head coach Bill Walsh and quarterback Joe Montana, who became the starter in week seven, replacing Steve DeBerg.

The 49ers looked to improve on their previous output of 2–14 (both of the two previous seasons); despite succeeding in improving their record, having posted a 6-10 record, they failed to make the playoffs for the eighth consecutive season.

On December 7, 1980, the 49ers rallied from down 35–7, scoring 31 unanswered points to defeat the winless New Orleans Saints in overtime. This was the last full season until 1999 that the 49ers finished with fewer than ten wins.
