The Pocomtuc (also Pocomtuck, Pocumtuc, Pocumtuck, or Deerfield Indians) were a Native American tribe historically inhabiting western areas of Massachusetts.

Their homelands also included much of current-day Hampden and Hampshire Counties, plus areas now in northern Connecticut and southern Vermont.

The fertile open meadows around present-day Deerfield were cleared and planted with corn, and dozens of short-term food storage pits pocked the surface of the glacial outcropping called Pine Hill.

In addition, they lost tribal members due to taking part in wars among the Dutch, English, French, and their respective Native American allies.

They remained there until the outbreak of the Seven Years' War in 1754, when most joined and merged into the Abenaki tribes at Saint-François-du-Lac, Quebec or moved further west.
