The 2011–12 New Jersey Devils season was the 38th season for the National Hockey League (NHL) franchise that was established on June 11, 1974, and 30th season since the franchise relocated from Colorado prior to the 1982–83 NHL season. The Devils hoped to return to the playoffs after having their long playoff streak snapped the previous year. While finishing fourth in the strong Atlantic Division, they ranked sixth in the Eastern Conference, thus securing a playoff berth, and faced the Southeast Division-winning Florida Panthers in the Conference Quarterfinals where they won in seven games. In the Conference Semifinals, the Devils played against the Philadelphia Flyers and won in five games. In the Conference Finals, they faced their rivals, the New York Rangers, and won in six games advancing to the Stanley Cup Final for the first time since the 2002–03 season. The Devils lost in the 2012 Stanley Cup Final to the Los Angeles Kings in six games.

Off-season The focus of the Devils during the 2011 off-season was on finding a new coach and player signings. The main focus of the team was resigning Zach Parise and signing fourth-overall 2011 pick Adam Larsson to an entry-level contract, although team CEO and General Manager Lou Lamoriello did find the time to sign goaltender Johan Hedberg, as well as defenseman Andy Greene. Additionally, the team chose to suspend operations of the Trenton Devils, which was a minor league ECHL club that the team had used for player development, citing declining fan interest in the team and a desire to bring the organization more in line with other NHL organizations in terms of minor league affiliations.

The Devils announced the hiring of Peter DeBoer as the new head coach of the team on July 19, 2011.

Pre-season On June 30, 2011, the New Jersey Devils announced that they would play six games during the pre-season. There were three home games at the Prudential Center against the New York Rangers, New York Islanders and Philadelphia Flyers. They also played two road games, one against the Islanders at Nassau Coliseum and one against the Flyers at Wells Fargo Center. One neutral site game against the Rangers took place at the Times Union Center, located in Albany, New York.

Regular season The Devils had a very effective penalty kill during the regular season, allowing the fewest shorthanded goals in the League (27) and having the highest penalty-kill percentage (89.58%). The 89.58% penalty kill is the best penalty kill by any team in a season in NHL history. They also scored the most shorthanded goals in the NHL (15) and allowed the most shorthanded goals in the League (13).

December 17, 2011 – Patrik Eliáš scores goals 347 and 348, surpassing John MacLean as the Devils' leading goalscorer.

Playoffs The Devils clinched their 20th playoff berth in 22 seasons with a 5–0 win over the Carolina Hurricanes on March 31, 2012. They finished the regular season with 102 points, finishing fourth in the Atlantic Division and sixth in the Eastern Conference. The Devils finished the regular season as the 6 seed in the East with 102 points. Returning injured center Travis Zajac led the team's offense as they then proceeded to knock the Florida Panthers out of the playoffs in 7 games, winning game 6 in overtime with a goal from Zajac and another in double overtime in game 7 from Henrique. They moved on to play their division rivals, the Philadelphia Flyers, in the conference semifinals and were considered heavy underdogs in the series. They faced some early setbacks against the Flyers including a Game 1 overtime loss and the injury of all-star Ilya Kovalchuk. However the Devils rallied in Game 2 without their star forward, winning the game by a score of 4–1. Kovalchuk returned strong for Game 3 and his pass to Ponikarovsky gave the Devils a much needed overtime goal to win Game 3. The streak continued as the Devils would win 4 in a row to eventually defeat the Flyers and advance to the Eastern Conference Finals for the first time since 2003. The Devils would play the New York Rangers in the Conference Finals, a rematch of the 1994 series that resulted in a heartbreaking Game 7 overtime loss during Brodeur's rookie season. The series was highly publicized by the New York media and was a tough back-and-forth battle for the first four games, leaving the series split 2-2. The Devils' fourth line, which had been very successful throughout the playoffs, came through in Game 5 to help give the Devils a 3–2 lead in the series. The line consisted of players Ryan Carter, Stephen Gionta and Steve Bernier, all of which had been dropped from a professional roster at some point during the season. Emerging as playoff heroes, they tallied an impressive 19 points in the first three rounds. Despite constant comparisons to the 1994 series, the Devils and Brodeur rewrote history and claimed victory on May 25, 2012, as Henrique scored another series clinching overtime goal in Game 6 to advance the Devils to the Stanley Cup Final against the Los Angeles Kings. Facing the Kings in the Final, the Devils lost two consecutive overtime games at home and then game three in Los Angeles. However, the Devils managed to not be swept after losing the first three games in the series, but still lost the Cup in six games.
