Empress Duan (段皇后, personal name unknown) was the second wife of An Lushan, a general of the Chinese Tang dynasty and later emperor of his rebel state of Yan.
After he declared himself emperor of Yan in 756, she probably carried the title of empress, but historical records are not completely clear.
In 747, when Emperor Xuanzong of Tang gave An the honorary title as chief imperial censor, she was created a lady, with a rank rivaling the sisters of Emperor Xuanzong's favorite concubine Consort Yang Yuhuan.
In 755, An Lushan rebelled against Emperor Xuanzong's reign at Fanyang (范陽, in modern Beijing) and quickly advanced south, capturing the Tang eastern capital Luoyang later in the year.
In response to An's rebellion, Emperor Xuanzong executed his first wife Lady Kang and oldest son An Qingzong (安慶宗), both of whom were then at the Tang capital Chang'an.
