Albert III, Count of Namur

Albert III (c. 1027 – 22 June 1102) was the Count of Namur from 1063 until his death. He was the son of Count Albert II and Regelinde of Verdun.

Although he was not formally a duke, Albert is considered to have played the role of an acting Duke of Lower Lotharingia, or "vice duke", during part of his lifetime, while the king's young son Conrad was named as Duke. However he lost this position when Godfrey of Bouillon was given the duchy.
