2006 Calder Cup playoffs

The 2006 Calder Cup playoffs of the American Hockey League began on April 18, 2006. The sixteen teams that qualified, eight from each conference, played best-of-seven series for division semifinals, finals and conference finals. The conference champions played a best-of-seven series for the Calder Cup. The Calder Cup Final ended on June 15, 2006 with the Hershey Bears defeating the Milwaukee Admirals four games to two to win the ninth Calder Cup in team history.

Milwaukee's Darren Haydar set an AHL post-season record by scoring 6 game-winning goals in a single playoff. Hershey's Frederic Cassivi tied an AHL record by recording 16 wins in one playoff. He also won the Jack A. Butterfield Trophy as AHL Playoff MVP.

Playoff seeds
After the 2005–06 AHL regular season, 16 teams qualified for the playoffs. The top four teams from each division qualified for the playoffs. However, it was possible for the fifth-placed team in the Atlantic Division to take the spot of the fourth-placed team in the East Division if they earned more points, since the East Division had one fewer team. This did not occur as the Bridgeport Sound Tigers, the fourth-placed team in the East Division finished with 85 points while the Lowell Lock Monsters, the fifth-placed team in the Atlantic Division, finished with 72 points. The Grand Rapids Griffins were the Western Conference regular season champions as well as the Macgregor Kilpatrick Trophy winners with the best overall regular season record. The Portland Pirates were the Eastern Conference regular season champions.
