Upper Sandusky was a 19th-century Wyandot town named for its location at the headwaters of the Sandusky River in the United States. This was the primary Wyandot town during the American Revolutionary War (1775–1783), and was sometimes also known as Half-King's Town, after Dunquat, the Wyandot "Half-King". The town and the surrounding settlements, like Captain Pipe's Town, were closely allied with the British at Fort Detroit.
