Density of 4,530 per square mile is the densest of any municipality in Hunterdon County (1st of 26) and 130th of 565 in NJ — making Flemington the most urban municipality in the entire county, with substantial walkable downtown character along Main Street and the surrounding historic corridors. Elevation 180 ft.
Flemington has one of the most distinguished municipal histories in central-western New Jersey. The borough is named after Samuel Fleming, the original settler whose Fleming Castle (Samuel Fleming House) was the very first house built in what became Flemington. In 1785, Flemington was chosen as the county seat for Hunterdon County — the main town where the county government would be located. A fire destroyed the original courthouse in 1826, and a new courthouse was subsequently constructed on Main Street that still stands today. Flemington officially became a "town" on March 14, 1870; it became a "village" on June 11, 1894; and following an April 26, 1910 referendum, the State formally incorporated Flemington as an independent borough — later confirmed April 27, 1931. The formal separation of Flemington from Raritan Township makes the two municipalities one of 21 pairs of "doughnut towns" in New Jersey — Raritan Township wraps completely around Flemington Borough.
Flemington's national notoriety is closely tied to the 1935 Lindbergh kidnapping trial — the trial of Bruno Hauptmann was held in the Flemington courthouse and became one of the most famous criminal proceedings in American history. The borough also hosted the Flemington Fair beginning in 1856 (when the Hunterdon County Agricultural Society purchased land for what became the County / Flemington Fair), the historic Flemington Fair Speedway, and later the Flemington Raceway. The South Branch of the Raritan River flows through the middle of town — one of the borough's most distinctive geographic features.
Government operates under the Borough form with a Borough Council legislative body. Mayor Marcia A. Karrow (R) currently serves a term ending December 31, 2026. Council President Tony Parker; Council Vice President Susan Engelhardt; Municipal Clerk Carla Conner. Borough Hall is located at 38 Park Avenue, Flemington 08822.

The Flemington-Raritan Regional School District at 50 Court Street serves PreK-8 across 6 schools — 4 elementary schools (Barley Sheaf, Copper Hill, Francis A. Desmares, and Robert Hunter), 1 intermediate school (Reading-Fleming Intermediate, grades 5-6), and 1 middle school (J. P. Case Middle School, grades 7-8). 3,174 students at an outstanding 9.5:1 student-teacher ratio, classified DFG I under Superintendent Kari McGann. For grades 9-12, Flemington students attend Hunterdon Central Regional High School (Red Devils) at 84 Route 31 — one of the largest, campus-style high schools in New Jersey with 2,246 students at 10.3:1, occupying a 72-acre campus and serving 5 municipalities: Flemington Borough, Raritan Township, Readington Township, Delaware Township, and East Amwell Township. 55% AP participation rate.

Flemington Borough's appeal rests on a distinctive combination of strengths producing the most urban municipality in Hunterdon County. First is county-seat heritage: Flemington has served as the county seat of Hunterdon County since 1785 — meaning over 240 years of continuous government and judicial activity centered in the borough. The historic Main Street courthouse (built after the original was destroyed by fire in 1826) is still in active use today, anchoring the borough's distinctive Main Street identity. Second is the Hunterdon Central Regional HS access: Flemington students attend the Red Devils — a comprehensive 9-12 regional high school serving 2,246 students on a 72-acre campus at 84 Route 31, one of the largest campus-style high schools in New Jersey with 55% AP participation. Hunterdon Central also serves Raritan, Readington, Delaware, and East Amwell townships under a unified regional structure. Third is the Flemington-Raritan Regional K-8 district: 6 schools, 3,174 students, and a remarkable 9.5:1 student-teacher ratio (one of the lowest in central New Jersey), classified DFG I under Superintendent Kari McGann. Fourth is borough density and walkable downtown: at 4,530 residents per square mile — the densest of any Hunterdon municipality (1st of 26) and 130th of 565 in NJ — Flemington offers genuine walkable Main Street character that no other Hunterdon municipality can match.
For buyers, this combination produces a market where median sale around $625K reflects the substantial premium of being the only walkable downtown county-seat borough in Hunterdon — combined with comprehensive K-12 access through Flemington-Raritan + Hunterdon Central, the historic Main Street identity (Fleming Castle, Union Hotel, the courthouse), and the borough's distinctive "doughnut" relationship with Raritan Township that wraps completely around it.
Flemington has been the county seat of Hunterdon County for over 240 years — since 1785. The historic Main Street courthouse (built after the 1826 fire) is still in active use today. The 1935 Lindbergh kidnapping trial of Bruno Hauptmann was held here.

The historic Main Street courthouse anchors Flemington's identity as the Hunterdon County seat since 1785. The original courthouse was destroyed by fire in 1826; the replacement courthouse on Main Street is still in active use today as the county's primary judicial facility. The courthouse became internationally famous in 1935 when it hosted the trial of Bruno Hauptmann for the Lindbergh kidnapping — one of the most consequential criminal proceedings in American history, often called "the trial of the century" at the time. The courthouse and surrounding Main Street remain a focal point of the borough's distinctive historic identity.
Fleming Castle, also known as the Samuel Fleming House, was the very first house built in Flemington. The borough is named after Samuel Fleming — the original settler whose home became the foundational structure around which the rest of the borough's pre-Revolutionary and 19th-century development organized. Fleming Castle anchors Flemington's substantial pre-Revolutionary architectural heritage and provides a tangible connection to the borough's original colonial-era settlement.

The fairgrounds also hosted the Flemington Fair Speedway, which later became the Flemington Raceway — a popular dirt-track racing venue that drew substantial crowds throughout the mid-20th century. The legacy fairgrounds site remains an important part of the borough's commercial and cultural heritage.
Flemington Borough is geographically surrounded on all sides by Raritan Township — making Flemington and Raritan one of New Jersey's 21 pairs of "doughnut towns" (where one municipality completely encloses another). Flemington Borough was formally separated from Raritan Township following the April 26, 1910 referendum that incorporated Flemington as an independent borough (later confirmed April 27, 1931). Today, Flemington and Raritan share the unified Flemington-Raritan Regional K-8 school district, and both municipalities are sending districts of Hunterdon Central Regional HS. The two municipalities function as effectively a single community served by independent governments — Flemington Borough (1.08 sq mi, 4,876 residents, dense and walkable) at the center, with Raritan Township (much larger, more residential) wrapping around it.
