Richenza of Northeim (c. 1087/1089 – 10 June 1141), a member of the comital House of Northeim, was Duchess of Saxony from 1106, German queen (formally Queen of the Romans) from 1125 and Holy Roman Empress from 1133 until the death of her husband Lothair of Supplinburg in 1137.
She was the daughter of Count Henry the Fat of Northeim (d. 1101) and Gertrude of Brunswick, daughter of the Brunonid margrave Egbert I of Meissen.
Around 1107 Richenza married Lothair of Supplinburg, who upon the death of the last Billung duke Magnus was enfeoffed with the Duchy of Saxony by King Henry V of Germany in 1106. After Lothair was elected King of the Romans in 1125, she was crowned queen consort by Archbishop Frederick I of Cologne. Richenza took an active part in her husband's reign, which is reflected in her activities during the papal schism of 1130, and her role as intermediary between Lothair and his Hohenstaufen rivals, the proclaimed antiking Conrad III and his brother Duke Frederick II of Swabia. In 1132-33 she accompanied her husband to Italy, both were crowned emperor and empress by Pope Innocent II at the Lateran Basilica in Rome on 4 June 1133. She also took part in Lothair's second Italian expedition in 1136-37, whereby she presided over hearings of the Imperial court and issued several deeds.
