Liang Lanbi (梁蘭璧; 300–311) was an empress during the Jin dynasty. Her husband was the ill-fated Sima Chi (Emperor Huai). Volume 138 of Taiping Yulan had a short biography on her, citing the Book of Jin authored by Zang Rongxu. She was also the last empress of the Western Jin, as her husband's successor Emperor Min was not recorded to have an empress during his reign. Very little is known about her, and she was not even listed in the biographies of the empresses in the Book of Jin, the official history of the dynasty. She was from Anding, and her father was Liang Fen (梁芬), son of Liang Hongji (梁鸿季). She had married Sima Chi long before he became emperor (most probably during his tenure as Prince of Yuzhang, although the date is not known). When he was crown prince from February 305 to January 307, she carried the title of crown princess. When he became emperor on 11 January 307, she was created empress. Nothing further is known about her, including her fate when both she and her husband were captured by Han-Zhao forces in July 311. However, it appeared that at least by later that year, when the Han-Zhao emperor Liu Cong created him the Duke of Kuaiji, she had either died or had been taken elsewhere, for Liu Cong gave a concubine of his, Consort Liu, to be the former Jin emperor's duchess. Qing dynasty scholar Xue Fucheng said Empress Liang committed suicide in defence of her virtue.
