The Hui people (Chinese: 回族; pinyin: Huízú; Wade–Giles: Hui²-tsu², Xiao'erjing: خوذو, Dungan: Хуэйзў, Xuejzw) are an East Asian ethnoreligious group predominantly composed of Chinese-speaking adherents of Islam. They are distributed throughout China, mainly in the northwestern provinces and in the Zhongyuan region. According to the 2011 census, China is home to approximately 10.5 million Hui people. The 110,000 Dungan people of Kazakhstan and Kyrgyzstan are also considered part of the Hui ethnicity.

The Hui have a distinct connection with Islamic culture. For example, they follow Islamic dietary laws and reject the consumption of pork, the most commonly consumed meat in China, and have developed their own variation of Chinese cuisine. They also dress differently than the Han Chinese, some men wear white caps (taqiyah) and some women wear headscarves, as is the case in many Islamic cultures.

The Hui people are one of 56 ethnic groups recognized by China. The government defines the Hui people to include all historically Muslim communities not included in China's other ethnic groups; they are therefore distinct from other Muslim groups such as the Uyghurs. The Hui predominantly speak Chinese, while maintaining some Arabic and Persian phrases. The Hui ethnic group is unique among Chinese ethnic minorities in that it is not associated with a non-Sinitic language.
