Mu Sheng (Chinese: 沐晟; Vietnamese: Mộc Thạnh; 1368–1439), courtesy name Jingmao (景茂), was a Chinese military general and politician of the Ming dynasty. Mu Sheng was the second son of Mu Ying, the first Marquis of Xiping (西平侯). He was a solemn man of few words, and the Hongwu Emperor very liked him. In 1399, his elder brother died without heir, so Mu Sheng succeeded him as Marquis of Xiping.
