The 1971 Kansas City Chiefs season was the franchise's second season in the National Football League (NFL), ninth as the Kansas City Chiefs, and twelfth overall. They improved from a 7–5–2 campaign in 1970 to record a 10–3–1 mark and win the AFC West division championship, the Chiefs' first division title since 1966 and last until 1993. The Chiefs tied with the Miami Dolphins for the best record in the AFC and were tied for the third-best record overall in the NFL, trailing only the 11–3 marks of the Dallas Cowboys and Minnesota Vikings.
