The New Hampshire Grants or Benning Wentworth Grants were land grants made between 1749 and 1764 by the provincial governor of New Hampshire, Benning Wentworth. The land grants, totaling about 135 (including 131 towns), were made on land claimed by New Hampshire west of the Connecticut River, territory that was also claimed by the Province of New York. The resulting dispute led to the eventual establishment of the Vermont Republic, which later became the U.S. state of Vermont.
The territory of what is now Vermont was first permanently settled by European settlers when William Dummer, acting governor of the Province of Massachusetts Bay, ordered the construction of a fort roughly where Brattleboro is located. Massachusetts laid claim to the territory west of the Merrimack River at the time, and it had settlers on the Connecticut River who were prepared to move further north. The border between Massachusetts and the neighboring Province of New Hampshire was fixed by royal decree in 1741 at a line 3 miles (4.8 km) north of Pawtucket Falls, where the Merrimack River turns north. This decision eliminated claims by Massachusetts to the north of that line. The territory between the Connecticut River and Lake Champlain, however, was also claimed by the Province of New York, whose claims extended eastward to the Connecticut.
