Michael Dean Bossy (January 22, 1957 – April 15, 2022) was a Canadian professional ice hockey player with the New York Islanders of the National Hockey League. He spent his entire NHL career, which lasted from 1977 to 1987, with the Islanders, and was a crucial part of their four consecutive Stanley Cup championships in the early 1980s.
Bossy won the Calder Memorial Trophy in 1978 as NHL rookie of the year when he set the then-record for most goals by a rookie with 53. He won the Conn Smythe Trophy in the 1982 Stanley Cup playoffs as the most valuable player and the Lady Byng Trophy for combining high quality play with sportsmanship three times. He led the NHL in goals twice and was second three other times. Bossy was voted to the league's first all-star team as right wing five times, with three further selections to the second all-star team.
