2018–19 New York Islanders season

The 2018–19 New York Islanders season was the 47th season in the franchise's history. It will be their fourth season in the Barclays Center in the New York City borough of Brooklyn, which they moved into after leaving Nassau Coliseum in Nassau County on Long Island at the conclusion of the 2014–15 season. The Islanders also use Nassau Coliseum as a part-time venue starting this year where they will play half of their 41 regular season home games, and as well as all First Round playoff home games. The Islanders entered the season looking to improve on their 35–37–10 record from the previous season, as well as make the playoffs for the first time since the 2015–16 season. They were able to improve their performance, despite losing their longtime captain and franchise player John Tavares in free agency. The Islanders clinched a playoff spot on March 30, 2019, with a 5–1 win against the Buffalo Sabres. On April 16, the Islanders swept the Pittsburgh Penguins in the first round, making it their first playoff series sweep since the 1983 Stanley Cup playoffs. However, in the second round, the Islanders were not able to capitalize on their success against Pittsburgh, as they were swept by the Carolina Hurricanes.
