The 1988 Kansas City Chiefs season was the franchise's 19th season in the National Football League and the 29th overall. Bill Kenney opened the team's initial two games at quarterback, but was replaced by Steve DeBerg for the second half against Seattle. DeBerg guided the team to a 20–13 win against Denver in his initial start as a member of the Chiefs. However, six losses, and a tie followed as Kenney and DeBerg jostled for the starting job.
