Allenstown is a small, rural town with a population centered around the old mills near the confluence of the Suncook and Merrimack Rivers, hence the old name of Suncook still used on some road maps. Downtown Pembroke forms the other half of Suncook Village. Originally settled in 1722, Allenstown was incorporated in 1831.

Natural borders are formed by the Merrimack River on the western side and the Suncook River on the northern side. To the north is Concord, the state capital; to the south is Manchester, the state's largest city. Route 28 leads northeast to Alton Bay, Wolfeboro, and the Lakes Region.

Today the intersection of Routes 3 and 28 can be considered the crossroads of the town. Most town businesses are located near that intersection.

Allenstown is also home to Bear Brook State Park, the largest of the New Hampshire state parks at over 10,000 acres. The park offers an amazing amount of recreational opportunities for the outdoor enthusiast.
