The governor of Formosa (Dutch: gouverneur van Formosa; Chinese: 台灣長官) was the head of government of Taiwan during the Dutch colonial period, which lasted from 1624 to 1662.

Appointed by the governor-general of the Dutch East Indies in Batavia (now Jakarta, Indonesia), the governor of Formosa was empowered to legislate, collect taxes, wage war and declare peace on behalf of the Dutch East India Company (VOC) and therefore by extension the Dutch state.

There were a total of twelve governors during the Dutch colonial era.

[1] The man sometimes said to be the thirteenth, Harmen Klenck van Odessen, was appointed by VOC Governor-General Joan Maetsuycker, only to arrive off the coast of Tayouan during the Siege of Fort Zeelandia.

Klenck refused to go ashore to take up his post despite being urged to by Frederick Coyett, the incumbent governor, and finally left without ever setting foot on Formosa.
