Richenza of Northeim (c. 1087/1089 – 10 June 1141) was a member of the dynasty of the Counts of Northeim, and a German Empress.
She was the daughter of Henry the Fat of Northeim (d. 1101) and Gertrud of Brunswick of the Brunonen dynasty.
Around 1100 Richenza married Lothar von Süpplingenburg, Duke of Saxony and future Holy Roman Emperor. Their daughter, Gertrud of Süpplingenburg was born in 1115; she later married Henry the Proud, Duke of Bavaria (d. 1139). This act brought both the Northeim and Brunonen lands into the hands of the Welf dynasty. Richenza died on 10 June 1141.
