The award is presented annually to the most valuable player in the NHL, as voted by fellow members of the National Hockey League Players' Association.
The three centres are also the finalists for the Hart Trophy, awarded by the NHL to the player considered most valuable to his team.
Crosby scored 36 goals and led the league in assists (68) and points (104) to capture his second career Art Ross Trophy and lead the Penguins to their second consecutive division title.
He registered points in 60 of the 80 games he played in (75 per cent), including 30 multi-point performances, and never went more than two consecutive games without registering a point.
The 26-year-old Cole Harbour, N.S., native also reached the 100-point milestone for the fifth time hit 700 career points in his 497th game, the fastest among active players and sixth-fastest in NHL history.
Crosby won the award in 2007 and 2013 and was a finalist in 2010.
