John Clark LeClair (born July 5, 1969) is an American former professional ice hockey player.

He played 16 seasons in the National Hockey League (NHL) with the Montreal Canadiens, Philadelphia Flyers, and Pittsburgh Penguins from 1991 to 2006.

With the Flyers, LeClair became the first American-born player to score 50 goals in three consecutive NHL seasons while playing on the Legion of Doom line with Eric Lindros and Mikael Renberg.

He is the son of Robert "Butch" LeClair, a manager of a paint store, and Beverly (Clark), a surgical nurse.

[2]Richard Benoit, the father of John's friend Jeremy, created a homemade rink for the kids in his backyard by flooding his volleyball court.

[2] When LeClair was a freshman at Bellows Free Academy, he didn't make the very competitive high school team.

College scouts began to take notice when he participated as a junior in Hockey Night in Boston, a showcase for young talent.

One of the most highly recruited hockey players in New England, LeClair put his NHL aspirations on hold to attend the University of Vermont on a full scholarship.

On February 9, 1995, a Montreal team desperate to salvage a difficult season traded LeClair, along with Éric Desjardins and Gilbert Dionne to the Philadelphia Flyers in exchange for Mark Recchi and Philadelphia's third round choice in the 1995 NHL Entry Draft (Martin Hohenberger).

LeClair gelled immediately with new line-mate Eric Lindros and quickly became one of the NHL's most feared goal scorers.

With the Flyers, he played left-wing on the famed "Legion of Doom" line, centered by Lindros and Mikael Renberg on right-wing.
