Hackettstown is a town in Warren County in the Skylands region of New Jersey in the Mid-Atlantic region of the United States.
Because Hackettstown is relatively smaller geographically than most other municipalities in the area, some of the attractions listed here could legally be in the municipalities of Mansfield Route 57, Independence New Jersey 517/46, Allamuchy 517/Waterloo Rd. or Washington Township, Morris County Route 46, but most are in or are close to walking distance from Hackettstown. These townships are considerably less developed. Most of the commercial development of the townships are located near the Hackettstown border.
