The 2005–06 New Jersey Devils season was the team's 24th in the National Hockey League since the franchise moved to New Jersey. It was the team's first season back after the NHL canceled the previous season, due to the 2004–05 NHL lockout. The Devils rallied from a poor first half of the season to win the Atlantic Division title on the last day of the season. For the first time, the Devils defeated the New York Rangers in a playoff series, sweeping their rivals in their opening-round matchup.
