The noontime unveiling of the statue -- called "Le Magnifique" -- outside the northwest gate at Consol Energy Center will be open to the public. The Penguins will host the Toronto Maple Leafs later that night.
Lemieux scored 690 goals and assisted on 1,033 others during his Hall of Fame career, all with Pittsburgh. He led the Penguins to consecutive Stanley Cups in the 1990-91 and 1991-92 seasons.
He became part of the ownership group that saved the franchise from relocation.
The bronze statue is designed by sculptor Bruce Wolfe.
The statue was funded privately by the Penguins' ownership group, local labor organizations and members of the Pittsburgh business community.
