The Monadnock Region is a region in southwestern New Hampshire. It is named after Mount Monadnock, a 3,165 foot isolated mountain, which is the dominant geographic landmark in the region. Although it has no specific borders, the Monadnock Region is generally thought of comprising all of Cheshire County and the western portion of Hillsborough County.

In addition to the frequently hiked Mount Monadnock, the region offers abundant opportunities for outdoor recreation, including four New Hampshire state parks. Pisgah State Park consists of 13,300 acres (5,400 ha) of forest, seven protected ponds popular for fishing, and six trails that may be used for hiking, mountain biking, ATVs, and snowmobiles. The Monadnock Region also boasts four recreational rail trails, lakes with public swimming beaches, and three ski areas.
