Frederick Coyett, born in Stockholm c. 1615 or 1620, buried in Amsterdam on 17 October 1687, was a Swedish nobleman and the last colonial governor for the Dutch colony of Formosa. He was the first Swede to travel to Japan and China and became the last governor of Dutch-occupied Taiwan (1656–1662).

The island of Taiwan, also commonly known as Formosa, was partly under colonial rule by the Dutch Republic from 1624 to 1662 and from 1664 to 1668. In the context of the Age of Discovery, the Dutch East India Company established its presence on Formosa to trade with the Ming Empire in neighbouring China and Tokugawa shogunate in Japan, and also to interdict Portuguese and Spanish trade and colonial activities in East Asia.
