Taishanese, or Toishanese (; Taishanese: ), is a dialect of Yue Chinese. The dialect is closely related to Cantonese. Taishanese is spoken in the southern part of Guangdong Province in China, particularly in and around the city-level county of Taishan. In the mid to late 19th century, a significant number of Chinese emigrating to North America originated from this area, making Taishanese a dominant variety of the Chinese language spoken in North American Chinatowns. It was formerly the lingua franca of the overseas Chinese residing in the United States. It is not currently recognized as having official status in any country.
