Lady Xiao (personal name unknown), also known as Yileilan (伊勒兰) was a Khitan noble lady of imperial China's Liao dynasty.
In 960, Yelü Xiyin plotted a rebellion against then-reigning Emperor Muzong (Emperor Taizong's son Yelü Jing).
As a result, both he and Yelü Lihu were arrested and placed in jail.
However, Yelü Xiyin later planned another rebellion against Emperor Jingzong.
He was captured, and his son with Lady Xiao was murdered by Liao troops.
