Jones Brook is a 10.6-mile-long (17.1 km)  stream located in eastern New Hampshire in the United States. It is a tributary of the Branch River, which leads to the Salmon Falls River, part of the Piscataqua River watershed leading to the Atlantic Ocean.
Jones Brook rises in the Moose Mountains, on the border between Brookfield and Middleton, New Hampshire, and flows southeast through Middleton. Upon entering Milton, the stream turns back to the northwest and joins the Branch River downstream from the village of Union.
