The 1993 Calder Cup playoffs of the American Hockey League began on April 12, 1993. The twelve teams that qualified, four from each division, played best-of-seven series for division semifinals and division finals. The highest remaining seed received a bye for the third round while the other two remaining teams played a best-of-three series, with the winner advancing to play the bye-team in a best-of-seven series for the Calder Cup. The Calder Cup Final ended on May 30, 1993, with the Cape Breton Oilers defeating the Rochester Americans four games to one to win the first Calder Cup in team history.
Cape Breton's Bill McDougall won the Jack A. Butterfield Trophy as AHL playoff MVP. He also set or tied five individual AHL playoff records during Cape Breton's Calder Cup run. He set the records for most points in one playoff (52; 26 goals, 26 assists), most goals scored in one playoff (26), and the most goals scored in one game with 5 in Cape Breton's 8-2 win over St. John's in game 4 of the Atlantic division final. McDougall also set the record for most assists in one playoff with 26, which has been matched twice since then. He also scored 7 points (4 goals, 3 assists) in game 2 of the semifinal against Springfield, tying an AHL record for most points in one playoff game. Cape Breton also tied an AHL playoff record by scoring 85 goals during the 1993 playoffs, and they managed to do it in one fewer game than the Sherbrooke Canadiens, who scored 85 goals during the 1987 Calder Cup Playoffs.
In each round the team that earned more points during the regular season receives home ice advantage, meaning they receive the "extra" game on home-ice if the series reaches the maximum number of games. For the Semifinal round, the team that earned the most points during the regular season out of the three remaining teams receives a bye directly to the Calder Cup Final. There is no set series format due to arena scheduling conflicts and travel considerations.
