Albert III, Count of Namur

Albert III (born c. 1027; died 29 July 1102) was the Count of Namur from 1063 until his death. He was the son of Count Albert II and Regelinde of Verdun.

From 1071 to 1072, he helped Richilde, Countess of Hainaut and Flanders fight against Robert the Frisian, but the Countess was beaten and lost Flanders.

In 1076, supported by Matilda of Tuscany, he claimed the Duchy of Bouillon, claiming to have rights by his mother, and fought against Godfrey of Bouillon to assert his claims. During a battle near Dalhem, he killed Hermann II, Count Palatine of Lotharingia (20 September 1085), making him fall out of favor with the German emperor. Finally, with the Truce of God in 1086, the Bishop of Liège succeeded in making peace between the warring parties in favor of Godfrey.

In 1099, Otbert, Bishop of Liege gave him the county of Brunengeruz.

In 1065 he married Ida (d. 1102), widow of Frederick of Luxembourg, Duke of Lower Lorraine, and daughter of Bernard II, Duke of Saxony. They had 5 children
