Dover is a town in Morris County, New Jersey, on the Rockaway River about 31 miles west of New York City and 23 miles west of Newark. With a 2020 population of 18,460 packed into roughly 2.7 square miles, it is one of the county's most densely settled municipalities and a distinct contrast to the suburban townships around it. Dover's identity is built on industry and the railroad: in the nineteenth century it became the most important industrial town in Morris County, with iron works and factories clustered along the river and a rail network that made it a regional freight and passenger hub. That industrial and railroad heritage still shapes the town today. The Blackwell Street Historic District anchors the commercial and civic center, and the Dover & Rockaway River Railroad continues the town's long association with railroading. The NJ Transit Dover Station sits at the western end of the Morris & Essex Line, giving residents a direct, one-seat rail commute toward Newark and New York — a defining advantage for a town of its size. Dover has evolved into a diverse, working- and middle-class community with a walkable downtown of shops, restaurants, and civic buildings. Route 46 passes just south of the station area, and nearby Route 80 and Route 287 tie the town into northern New Jersey's highway network. Public schools are operated by Dover Public Schools, a compact PreK–12 district serving the town's families. For buyers and renters, Dover offers urban-style density, transit access, and a historic main-street feel at a scale that remains distinctly small-town. It suits commuters and families who want a walkable New Jersey town with a direct rail line to Manhattan and a deep sense of place. The town pairs nineteenth-century character with one of the region's most practical commutes.
