Tua Pek Kong is a Taoist deity in the pantheon of Peranakan folk religion practiced by ethnic Chinese in Malaysia, Singapore, and parts of Indonesia.

Chinese folk religion plays a dynamic role in the lives of the overseas Chinese who have settled in the countries of this geographic region, particularly Burmese Chinese, Singaporean Chinese, Malaysian Chinese, Thai Chinese and Hoa. The Indonesian Chinese, by contrast, were forced to adopt en masse either Buddhism or Christianity in the 1950s and 1960s, abandoning traditional worship, due to Indonesia's religious policies which at the time forbade Chinese traditional religion or did not recognize it as a "religion," thus making it vulnerable to discrimination. Some Chinese Filipinos also still practice some Chinese traditional religions, besides Christianity of either Roman Catholicism or Protestantism, with which some have also varyingly syncretized traditional Chinese religious practices. Chinese folk religion, the ethnic religion of Han Chinese, "Shenism" was especially coined referring to its Southeast Asian expression; another Southeast Asian name for the religion is the Sanskrit expression Satya Dharma.
