2023 Kansas City Chiefs season

The 2023 season was the Kansas City Chiefs' 54th season in the National Football League (NFL), their 64th overall and their eleventh under head coach Andy Reid.

The Chiefs, who entered the season as defending champions, became the first team to repeat as Super Bowl champions since the New England Patriots in 2003 and 2004 along with being the second AFC West team to repeat as Super Bowl champions since rival Denver Broncos in 1997 and 1998. Although they failed to improve on their 14–3 record from the previous season, they secured their eleventh consecutive winning season and became division champions for the eighth consecutive season.

In the playoffs, they made their sixth consecutive AFC Championship Game appearance, but their first on the road, defeating the Baltimore Ravens 17–10 to advance to their fourth Super Bowl in 5 years. They defeated the San Francisco 49ers 25–22 in overtime in Super Bowl LVIII, which was only the second overtime in Super Bowl history and a rematch of Super Bowl LIV. The Chiefs defense was a key part of their Super Bowl-winning season, as they had a 2nd ranked defense in terms of yardage and points per game, only behind the Ravens. Despite all four of their opponents in the playoffs having scoring offenses that finished in the top 10 in the NFL, the Chiefs only allowed 15.8 points per game in the playoffs.

NFL Top 100
The Chiefs only had three players ranked in the NFL Top 100 Players of 2023 players for the second straight year. However, all three were ranked in the top 10. Patrick Mahomes was named the number 1 player for the 2nd time. They were the only team with multiple top 10 selections and the second team ever with three in the top 10, after the Los Angeles Rams in 2022.
