On January 5, 1975, the North Stars decided to trade the aging Parisé to the New York Islanders in exchange for Doug Rombough and Ernie Hicke. While he was with the Islanders, he was able to help them reach their first playoff berth that season and was also able to help them reach the Stanley Cup semifinals, where they were defeated in a seven-game series by the eventual Stanley Cup champions Philadelphia Flyers.
