  Yes.
  
  FIDE Laws of Chess, rule `3.7e`:
  
  > When a pawn reaches the rank furthest from its starting position it must be exchanged as part of the same move on the same square for a new queen, rook, bishop or knight of the same colour.
  
  [The Wikipedia article on promotion](http://en.wikipedia.org/wiki/Promotion_%28chess%29#1862_British_Chess_Association_rule) contains some information about the history of the rule, which previously implicitly allowed promotion to a piece of the opposite color.
