The township spans 37.05 square miles (36.66 land + 0.39 water = 1.06%) — making Delaware the 3rd-largest municipality in Hunterdon by area, 65th of 565 statewide. Density of just 124.4 per square mile (25th of 26 county — among the lowest in the entire county) reflects Delaware's character as one of the most genuinely rural municipalities in central New Jersey. Elevation 371 ft. Farming remains a major occupation throughout the township's substantial agricultural footprint.
Delaware Township was first settled in the early 18th century by Colonel John Reading (1657-1717) — the same colonial figure for whom Readington Township is named. Reading was instrumental in the creation of Amwell Township in 1708 (the first township in what would become Hunterdon County in 1714) and in the creation of Hunterdon County itself. Delaware was incorporated as a township by an act of the New Jersey Legislature on April 2, 1838 from the now-defunct "Old Amwell Township" — alongside East Amwell, West Amwell, and Raritan townships, the four municipalities that divided Old Amwell after 130 years of unified governance. On April 14, 1898 a portion of Delaware Township was taken to form Stockton Borough. The township is named after the Delaware River, which runs along its southwestern side and separates Delaware Township from Plumstead and Solebury townships in Bucks County, Pennsylvania.
Delaware Township's geography spans two distinctive regions. Part of the township sits on the Hunterdon Plateau (higher elevation upland), while the southern portions sit in the Amwell Valley (lower-elevation agricultural landscape). The township is bordered on the southwest by the Delaware River (across from Bucks County, PA); on the southeast roughly by the Alexsauken and Raritan Creeks; on the northeast by current Route 579 (the old Trenton-Easton Turnpike and former Native American trail); and on the northwest by Kingwood and Franklin townships. Within Hunterdon County, Delaware borders East Amwell, Franklin (Hunterdon), Kingwood, Lambertville City, Raritan, Stockton Borough, and West Amwell townships.
Government operates under the NJ Township form with a Township Committee body. Mayor Charles Herman (R) currently serves; Acting Municipal Clerk Diana Rumage. The Township Committee rotates the mayoral role annually among its members. The Municipal Building is 225 years old and located in the Village of Sergeantsville in the heart of the township.
Education in Delaware operates through a township-only PreK-8 district plus regional 9-12. The Delaware Township School District at 501 Rosemont-Ringoes Road in Sergeantsville serves PreK-8 in a single school — 410 students at a remarkable 8.9:1 student-teacher ratio, classified DFG GH. For grades 9-12, Delaware students attend Hunterdon Central Regional High School (Red Devils) at 84 Route 31 in Flemington — one of the largest campus-style high schools in NJ with 2,246 students at 10.3:1 on a 72-acre campus, serving 5 municipalities (Flemington, Raritan, Readington, Delaware, and East Amwell townships) covering 152.5 sq mi and approximately 48,680 residents. 55% AP participation.

Delaware Township's appeal rests on a distinctive combination of strengths that make it one of the most historically significant rural municipalities in central New Jersey. First is the Green Sergeant's Covered Bridge legacy: Green Sergeant's is the only remaining historic covered bridge on a public road in all of New Jersey — added to the National Register of Historic Places on November 19, 1974 (#74001165). Constructed in 1872, rebuilt and reinforced in 1961, the bridge crosses the Wickecheoke Creek between Sergeantsville and Rosemont and serves as the township's official seal. Second is the 8 historic villages and hamlets: Sergeantsville (the largest, most central, and the seat of government), Headquarters and Sand Brook (eastern), Sandy Ridge and Locktown (center), and Rosemont, Raven Rock, and Brookville (western) — plus Bowne, Dilts Corner, Grover, and Prallsville — preserving the substantial historic village character that defines Delaware Township. Third is the Hunterdon Central HS access: Delaware students attend the Red Devils — a comprehensive 9-12 regional high school with 2,246 students on a 72-acre campus, 55% AP, US News 117th in NJ — alongside Flemington, Raritan, Readington, and East Amwell. Fourth is Delaware River frontage: the township is bounded on the southwest by the Delaware River across from Bucks County, PA — with the D&R Canal paralleling the southern border, Bull's Island State Park (canoe launch and exit), and substantial scenic-river-corridor character.
For buyers, this combination produces a market where median sale around $695K reflects substantial value for one of New Jersey's most genuinely rural municipalities — 3rd-largest Hunterdon by area at just 124.4 per square mile density (2nd-lowest in the county), with the only covered bridge in NJ on a public road, 8 historic villages, comprehensive K-12 access through the Delaware Township School District + Hunterdon Central Red Devils, and Delaware River + D&R Canal scenic corridor.

Green Sergeant's Covered Bridge is the only remaining historic covered bridge on a public road in the entire state of New Jersey — added to the National Register of Historic Places on November 19, 1974 (NRHP reference #74001165) for its significance in engineering and transportation. The bridge was constructed in 1872 and was rebuilt and reinforced in 1961. It crosses the Wickecheoke Creek between Sergeantsville and Rosemont — near the natural border between the Hunterdon Plateau (north) and the Amwell Valley (south). The bridge serves as Delaware Township's official municipal seal — one of the most distinctive municipal seal images of any New Jersey township. The bridge is one of just two surviving covered bridges in NJ (the other is the Scarborough Bridge in Cherry Hill, which is not on a public road).
Sergeantsville is Delaware Township's largest, most central, and seat-of-government village. The Township's 225-year-old Municipal Building is located in Sergeantsville (at 225 years old as of 2026, the building dates to approximately 1801). The village is also home to the Delaware Township School District (501 Rosemont-Ringoes Road, the single PreK-8 school serving all township students), WDVR Radio, and several regionally popular dining establishments and businesses. On the 4th of July, visitors can witness the township's famous Great Crate Race. Sergeantsville's Post Office uses ZIP 08557.

Additional smaller communities include Bowne, Dilts Corner, Grover, Prallsville, and others. The hamlets and villages preserve substantial 18th- and 19th-century architectural character and reflect Delaware Township's identity as one of the most genuinely rural municipalities in central New Jersey.
The Covered Bridge Historic District is a 97-acre National Register-listed historic district along County Route 604, Pine Hill Road, and Lower Creek Road in Delaware Township. The district was added to the NRHP on March 5, 1999 (NRHP reference #99000269) and designated to the NJ Register of Historic Places on January 19, 1999 (NJRHP #104). Architectural styles within the district include Georgian and Colonial Revival — preserving the substantial 18th- and 19th-century character of the broader Green Sergeant's Covered Bridge corridor. The district complements and extends the protection around the Green Sergeant's Covered Bridge itself.
Delaware Township is bounded on the southwest by the Delaware River — across from Plumstead Township and Solebury Township in Bucks County, Pennsylvania. The Delaware and Raritan Canal parallels the Delaware River along the township's southern border, providing a substantial scenic-river-corridor and recreational identity. Bull's Island State Park (off Rt. 29 north of Stockton) is a popular launch and exit site for canoeists, anchoring the township's substantial Delaware River outdoor recreation infrastructure. Delaware Township's Delaware River frontage is one of the most distinctive geographic features in central Hunterdon County.
Delaware Township was first settled in the early 18th century by Colonel John Reading (1657-1717) — the same colonial figure for whom Readington Township is named. Reading was instrumental in the creation of Amwell Township in 1708 (the first township in what would become Hunterdon County) and in the creation of Hunterdon County itself in 1714.
