The 1991 Kansas City Chiefs season was the franchise's 22nd season in the National Football League and 32nd overall. They failed to improve on their 11–5 record from 1990 and finished with a 10–6 record. Compared to the Chiefs' 1990 campaign, Steve DeBerg’s consistency had dropped. The running game made up for lost time as Christian Okoye ran for 1,031 yards for the season, Barry Word was productive, and rookie Harvey Williams was outstanding in limited playing time. The Chiefs defeated their division rival, the Los Angeles Raiders in the Wild Card round, resulting in the franchise's first playoff victory since Super Bowl IV in 1970. The next week, the Chiefs lost to the Buffalo Bills in the divisional playoffs.
