The đồng has been the currency of Vietnam since May 3, 1978. Issued by the State Bank of Vietnam, it is represented by the symbol "₫". Formerly, it was subdivided into 10 hào, which was further subdivided into 10 xu, neither of which is now used.

The word đồng is from the term đồng tiền ("money"), a cognate of the Chinese tóng qián (Traditional Chinese: 銅錢; Simplified Chinese: 铜钱). The term refers to Chinese bronze coins used as currency during the dynastic periods of China and Vietnam. The term hào is a cognate of the Chinese háo (Chinese: 毫), meaning a tenth of a currency unit.
