Champion (; ) is a sub-municipality of the city of Namur located in the province of Namur, Wallonia, Belgium. It was a separate municipality until 1977. On 1 January 1977, it was merged into Namur.
The unincorporated area of Champion in Green Bay, Wisconsin in the United States was named for this town by Adele Brice, an emigré from that region; it hosts a shrine to a Marian apparition she experienced there.
