Mink Brook is a {{convert|9.5|mi|km|adj=mid|-long}} stream in western New Hampshire in the United States. It is a tributary of the Connecticut River, which flows to Long Island Sound.

Mink Brook lies entirely in the town of Hanover. It rises on the western slopes of Moose Mountain and flows west, through the village of Etna, before reaching the Connecticut just north of the Hanover-Lebanon municipal boundary.
