The 1983–84 New York Islanders season was the 12th season for the franchise in the National Hockey League. The Islanders entered to the season as the four-time defending Stanley Cup champions, and subsequently went the Stanley Cup Finals for the fifth time in a row, but lost four games to one in a rematch against the Edmonton Oilers. The Islanders nevertheless set a new North American major professional sports record by winning nineteen consecutive playoff series (two more than the seventeen series won by the Boston Celtics in their eight-year NBA championship dynasty) and unmatched in any major sport since.
