Vermont is a state in the New England region of the northeastern United States of America. The state ranks 45th by total area, and 43rd by land area at 9,250 square miles, and has a population of 608,827, making it the second least populous state (second only to Wyoming). The only New England state with no coastline along the Atlantic Ocean, Vermont is notable for the Green Mountains in the west and Lake Champlain in the northwest. It is bordered by Massachusetts to the south, New Hampshire to the east, New York to the west, and the Canadian province of Quebec to the north.

Originally inhabited by Native American tribes (Abenaki, and Iroquois), the territory that is now Vermont was claimed by France but became a British possession after France's defeat in the French and Indian War. For many years, control of the area was disputed by the surrounding colonies, notably between New Hampshire and New York. Settlers who held land titles granted by these colonies were opposed by the Green Mountain Boys militia, which eventually prevailed in creating an independent state. Vermont became the 14th state to join the United States, following a 14-year period during and after the Revolutionary War as the independent Republic of Vermont.

It is the leading producer of maple syrup in the United States. The state capital is Montpelier, and the largest city is Burlington.
