The 1979–80 Detroit Pistons season was the Detroit Pistons' 32nd season in the NBA and 23rd season in the city of Detroit. The Pistons were coming off a 30–52 (.366) record from their first season in the Eastern Conference, and aiming to halt declines of six and eight wins from their previous two seasons, but by finishing 16–66 (.195) they had the worst record in franchise history, and the worst NBA record since the 1972–73 Philadelphia 76ers won only nine games.
