The Vermont Senate is the upper house of the Vermont General Assembly, the state legislature of the U.S. state of Vermont. The Senate consists of 30 members. Senate districting divides the 30 members into three single-member districts, six two-member districts, three three-member districts, and one six-member district. Each Senator represents at least 20,300 citizens. Senators are elected to two-year terms, and there is no limit to the number of terms that a Senator may serve.

As in other upper houses of state and territorial legislatures and the federal U.S. Senate, the Senate is reserved with special functions such as confirming or rejecting gubernatorial appointments to executive departments, the state cabinet, commissions, boards, and electing members to the Vermont Supreme Court.

The Vermont Senate meets at the Vermont State House in Montpelier.

Senators are elected from a total of 13 single and multi-member Senate districts. The districts more or less correspond to the boundaries of the state's 14 counties with adjustments to ensure equality of representation. Two small counties (Essex and Orleans) are combined into one district. Each district elects between 1 and 6 senators depending on population.

Vermont ⁱ/vɜrˈmɒnt/ is a state in the New England region of the northeastern United States. Vermont is the 6th least extensive and the 2nd least populous of the 50 United States. It is the only New England state not bordering the Atlantic Ocean. Lake Champlain forms half of Vermont's western border, which it shares with the state of New York. The Green Mountains are within the state. Vermont 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 two major Native American tribes (the Algonquian-speaking Abenaki and the Iroquois), much of the territory that is now Vermont was claimed by France during its early colonial period. France ceded the territory to the Kingdom of Great Britain after being defeated in 1763 in the Seven Years' War (also called the French and Indian War). For many years, the nearby colonies, especially New Hampshire and New York, disputed control of the area (then called the New Hampshire Grants). 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, the Vermont Republic. Founded in 1777 during the Revolutionary War, the republic lasted for fourteen years. Vermont is one of seventeen U.S. states (along with Texas, Hawaii, the brief California Republic, and each of the original Thirteen Colonies) to have had a sovereign government in the past. In 1791, Vermont joined the United States as the 14th state, the first outside the original 13 Colonies. It abolished slavery while still independent, and upon joining the Union became the first state to have done so.
