The Luxembourgian Footballer of the Year is an award granted every season to a football player from Luxembourg's domestic top-flight National Division, rewarding the player judged to have been the most valuable to his team that season. It is awarded by the sports desk of d'Wort, Luxembourg's most-read daily newspaper. It has been awarded every year since 1988, and has been named the Guy Greffrath Challenge after Guy Greffrath, the long-time sports editor at d'Wort, since 1997.
