The team currently play in the National Division 1, the third tier of Belgian football.

They are often nicknamed Les Merles due to their colours black with a touch of yellow.

Until 2018, the team was known as UR Namur, however as the team faced relegation from the 2017–18 Belgian Third Amateur Division into the Belgian provincial leagues, the team instead merged with newly promoted Fosses to form Union Royale Namur Fosses-La-Ville and retain its place in the Belgian Third Amateur Division.

In 2021–22, the club renamed to Union Namur promotes to the Second Amateur Division (4th tier of Belgian football).
