The 2021–22 Toronto Maple Leafs season was the 105th season for the National Hockey League (NHL) franchise that was established on November 22, 1917. On April 9, 2022, the Maple Leafs clinched a playoff spot for the sixth year in a row with a 3–2 win against the Montreal Canadiens. With a 4–2 win over the New York Islanders on April 17, the Maple Leafs set franchise records in both wins (50) and points (106). The Maple Leafs qualified for the playoffs for the sixth consecutive season, but they were upset in the first round by the two-time defending Stanley Cup champion Tampa Bay Lightning, losing in seven games, despite leading the series 3–2 with a 3–2 lead after the 2nd period of Game 6. After the Florida Panthers winning a playoff series for the first time since 1996, Toronto held the NHL's longest active playoff series win drought, not having won a playoff series since 2004.
