Count Richar (or Richer, sometimes equated to the similar name "Richard") (died 16 October 972) was a 10th-century Lotharingian count. He had a well-attested county in the Luihgau, a territory between Liège and Aachen, and he is generally considered to have held comital status in the County of Hainaut, possibly in the area of Mons.
