Empress Xiaominrang (孝愍讓皇后; 1378–1402), of the Ma clan, was the empress consort to the Jianwen Emperor and the second empress consort of China's Ming dynasty.^[1]

Born in 1378, Ma was the daughter of an official from the town of Yingtian in modern Nanjing named Ma Quan (馬全). She married Zhu Yunwen, grandson of the Hongwu Emperor, and was proclaimed consort of the Imperial Grandson-heir (Chinese: 皇太孙妃; pinyin: Huáng Tàisūnfēi) in 1395.^[2]

Zhu Yunmen ascended the throne in 1398 and Ma was instated as the empress consort in the second month of his reign.^[3] She had two sons, Zhu Wenkui, Crown Prince Hejian and Zhu Wengui, Prince Huai of Run, both posthumously honored.

In 1402, Zhu Di sacked Nanjing and set fire to the palace, where Empress Ma died.^[4]
