The Manchukuo yuan (Chinese: 滿洲國圓, Mǎnzhōuguóyuán) was the official unit of currency of the Empire of Manchuria, from June 1932 to August 1945.

The monetary unit was based on one basic pure silver patron of 23.91 grams.

It replaced the Chinese Haikwan tael, the local monetary system in common and regular use in Manchuria before the Mukden Incident, as legal tender.

Initially banknotes and coins were produced and minted by the Bank of Japan, but were later issued from the mint of the Central Bank of Manchou in the Manchukuo capital of Hsinking (now Changchun) with branch offices in Harbin, Mukden, Jilin, and Qiqihar.

To keep up with the inflationary pressures typically experienced by Japanese-controlled areas towards the end of World War II, a 1,000 yuan note was issued in 1944.
