The 1986 San Francisco 49ers season was the franchise's 37th season in the National Football League and their 41st overall. The team returned to the top of the NFC West after a one-year absence, and lost in the divisional playoffs to the Giants, by a score of 49-3, possibly the biggest playoff loss suffered by the 49ers in the history of their franchise. This was the first of five consecutive NFC West titles for the 49ers.
Joe Montana suffered a back injury in Week 1 and was lost for two months after surgery. Because the injury was so severe, Montana's doctors suggested that Montana retire. However, Montana returned for Week 10 against the St. Louis Cardinals, where he passed for 270 yards and three touchdown passes in a 43–17 49er victory. Montana appeared in just eight games this season, and threw more interceptions than touchdown passes for the only time in his career. Montana shared Comeback Player of the Year honors with Minnesota's Tommy Kramer at the end of the season.
