The 2020 season was the San Francisco 49ers' 71st in the National Football League, their 75th overall, and their fourth under the head coach/general manager tandem of Kyle Shanahan and John Lynch. The 49ers entered the season as the defending NFC champions; however, the 49ers failed to improve on their 13–3 season after a Week 8 loss to the Seattle Seahawks and were eliminated from playoff contention after a Week 15 loss to the Dallas Cowboys.
