The đồng (Chữ Nôm: 銅; Chữ Hán: 元, nguyên)[a] (/ˈdɒŋ/; Vietnamese: [ɗôŋm]) was the currency of North Vietnam from 3 November 1946 to 2 May 1978.

The first đồng issued by the communists controlling northern Vietnam was introduced on January 31, 1946, and replaced the French Indochinese piastre at par.

In 1958, holed, aluminium coins in denominations of 1, 2 and 5 xu were introduced.

The government (Việt Nam Dân Chủ Cộng Hòa) issued two forms of paper money for this currency, "Vietnamese banknotes" (Giấy Bạc Việt Nam) and "Credit notes" (Tín Phiếu).

In 1951, the National Bank of Vietnam (Ngân hàng quốc gia Việt Nam) introduced notes for 20, 50, 100, 200, 500 and 1000 đồng, with 5000 đồng notes added in 1953.
