Who scored the fastest hat trick in NHL history?

Bill Mosienko scored the fastest hat trick in NHL history, putting three goals past the New York Rangers in just 21 seconds on March 23, 1952.

Mosienko achieved the record while playing right wing for the Chicago Black Hawks. All three goals came during the third period against Rangers goaltender Lorne Anderson. His linemate Gus Bodnar assisted on every goal, and Mosienko nearly scored a fourth only 45 seconds later when his shot hit the post.

The feat was especially remarkable because Mosienko was not a high-volume penalty or power forward. In 14 NHL seasons, he recorded only 121 penalty minutes and became known for speed, skill, and gentlemanly play. He spent his entire NHL career with Chicago and was inducted into the Hockey Hall of Fame in 1965.

A common mix-up is confusing a hat trick with three goals by one team in a short span. This record belongs specifically to one player scoring three times in 21 seconds, and it remains an NHL record.
