Islam has been practiced in China since the 7th century CE. Muslims are a minority group in China, representing around 2 percent of the total population. Though Hui Muslims are the most numerous group, the greatest concentration of Muslims are in Xinjiang, which contains a significant Uyghur population. Lesser yet significant populations reside in the regions of Ningxia, Gansu and Qinghai. Of China's 55 officially recognized minority peoples, ten of these groups are predominantly Sunni Muslim.

Islam is an Abrahamic monotheistic religion centered on the Quran and the teachings of Muhammad, the religion's founder. Adherents of Islam are called Muslims, who are estimated to number approximately 1.9 billion worldwide and are the world's second-largest religious population after Christians.
