Lamentation Mountain, or Mount Lamentation, 720 feet (220 m), is a traprock mountain located 2.5 miles (4.0 km) north of Meriden, Connecticut. It is part of the narrow, linear Metacomet Ridge that extends from Long Island Sound near New Haven, Connecticut, north through the Connecticut River Valley of Massachusetts to the Vermont border. Lamentation Mountain is known for its scenic vistas, extensive cliff faces, unique microclimate ecosystems, and rare plant communities. It rises steeply 550 feet (170 m) above the city of Meriden to the south with west-facing cliffs of 200 feet (61 m) or more. The cliff line, described by the Connecticut Forest and Park Association as "perhaps the most scenic traprock ridge walk in the state" is a prominent landscape feature visible for miles. The mountain is traversed by the 50-mile (80 km) Mattabesett Trail.
