Penacook is a village at the northern most part of the city of Concord, NH. The name comes from the Pennacook tribe that lived in the area. Penacook (Pennycook) was the original name of the plantation incorporated by present-day Concord.

Penacook is located along the Contoocook River which drops 100 feet in slightly over one mile, just before joining the Merrimack River. Early hydro-powered industry was attracted to the site, and Penacook grew into a mill town.
