Xiao Noujin (蕭耨斤; 980–1057) was a Khitan empress dowager of China's Liao dynasty. She was a concubine of Emperor Shengzong, the mother of Emperor Xingzong, and one of the three Liao grand empresses dowager. She had great influence after the accession of her son the throne in 1031. Background Xiao Noujin was born into poverty, but Yelü Longxu brought her into the palace. However, he never treated her as a concubine but instead gave her to his mother Xiao Yanyan as a court lady.
