The Boquet River (or Bouquet River before a 1982 Board on Geographic Names decision) is a small river in upstate New York, United States. The river flows into Lake Champlain at the east border of the Town of Willsboro in Essex County.

The Boquet River is 40 miles (64 kilometers) long. Its source is in the Adirondack Mountains, within the Adirondack Park.

In 1814, during the War of 1812, a small battle was fought at the mouth of the river.^{[citation needed]}
