The 2004-05Atlanta Hawks season was the team's 56th in the NBA. It was their first season under new head coach Mike Woodson. Even with the acquisitions of Antoine Walker and Al Harrington, the Hawks were not expected to be any good heading into the season as they posted an awful 2–12 record in November. At midseason, Walker was eventually traded to the Boston Celtics for Gary Payton, who was released and re-signed with the Celtics. Meanwhile, the Hawks went from bad to worse losing 31 of their final 35 games on their way to finishing with a league worst record at 13–69 (.159), which was their worst winning percentage in franchise history. Despite their awful season, rookie Josh Smith won the Slam Dunk Contest during the All-Star Weekend in Denver.
