The Metacomet Ridge, Metacomet Ridge Mountains, or Metacomet Range of southern New England, United States, is a narrow and steep fault-block mountain ridge known for its extensive cliff faces, scenic vistas, microclimate ecosystems, and communities of plants considered rare or endangered. An important recreation resource located within 10 miles (16 km) of a population corridor of over 1.5 million people, the ridge is home to four long-distance hiking trails and over a dozen parks and recreation areas including several state and nationally recognized historic sites. Because of its natural, historic, and recreational value, the ridge has been the focus of ongoing conservation efforts involving municipal, state, and national agencies and nearly two dozen non-profit organizations.

The Metacomet Ridge extends from New Haven and Branford, Connecticut, on Long Island Sound, through the Connecticut River Valley region of Massachusetts, to northern Franklin County, 2 miles (3 km) short of the Vermont and New Hampshire borders, a distance of 100 miles (160 km). Younger and geologically distinct from the nearby Appalachian Mountains and surrounding uplands, the Metacomet Ridge is composed of volcanic basalt, also known as trap rock, and sedimentary rock in faulted and tilted layers many hundreds of feet thick. In most but not all cases, the basalt layers are dominant, prevalent, and exposed. Although only 1,200 feet (370 m) above sea level at its highest, with an average summit elevation of 725 feet (221 m), the Metacomet Ridge rises dramatically from much lower valley elevations, making it a prominent landscape feature.
