The Teochew people or Chaoshanese, Teo-Swa people or Chaoshan people is an ethnic group native to the historical Chaoshan region in south China who speak the Teochew language. Today, most ethnic Teochew people live throughout Chaoshan and Hong Kong, and also outside China in Southeast Asia, including in Singapore, Malaysia, Thailand, Indonesia, Cambodia, Vietnam, and the Philippines. The community can also be found in diasporas around the world, including the United States, Canada, Australia, New Zealand, and France.

Chaoshan or Teoswa is a cultural-linguistic region in the east of Guangdong, China. It is the origin of the Min Nan Chaoshan dialect (潮汕话). The region, also known as Chiushan in Cantonese, consists of the cities Chaozhou, Jieyang and Shantou. It differs linguistically from the rest of Guangdong province, which was historically dominated by Yue speakers, Hakka, and Leizhou Min speakers. However, Mandarin has recently become the dominant language in the region. It is historically important as the ancestral homeland of many citizens of other countries of Chinese descent, including Viets, Thais, Cambodians, Singaporeans, Malaysians, and Indonesians.
