List of San Francisco 49ers seasons

This article is a list of seasons completed by the San Francisco 49ers, an American football franchise representing the San Francisco Bay Area. The 49ers are members of the West division in the National Football Conference (NFC) of the National Football League (NFL). The list documents the season-by-season records of the 49ers' franchise from 1946 to present, including postseason records, and league awards for individual players or head coaches. The San Francisco 49ers began play in 1946 as charter members of the All-America Football Conference. When the 49ers joined the NFL after the AAFC-NFL merger in 1950, they never won a division or conference title, and only finished as high as second once from 1950 to 1969. After winning three consecutive division titles from 1970 to 1972, they would return to losing in 1973 and achieved only one winning season for the rest of the decade. From 1981 to 1998, the 49ers had one of the most successful stretches of dominance in NFL history. During this run, they would win 5 Super Bowls and made the playoffs every year besides 1982. Another playoff drought lasted from 2003–2010, a stretch of eight non-winning seasons. This drought came to an end when the 49ers won their division with a 13–3 record in 2011, and from 2011 to 2013, they earned three straight berths in the NFC Championship Game, which included a trip to Super Bowl XLVII. They would have another stretch of losing seasons from 2014-2018 before an improbable 13-3 turnaround season in 2019 saw them win the NFC, but lose to the Chiefs in Super Bowl LIV.
