The 1999 season was the Kansas City Chiefs' 30th in the National Football League (NFL) and their 40th overall.
The season began with the promotion of defensive coordinator Gunther Cunningham to head coach following the resignation of Marty Schottenheimer after the Chiefs finished with a 7–9 record in 1998.
The team improved on that in 1999, finishing with a 9–7 record, which was good enough for second place in the AFC West.
However, the Chiefs were denied the division title and a playoff berth in the final game of the season against the Oakland Raiders, when Raiders kicker Joe Nedney kicked a field goal in overtime.
