The Rockaway River is a tributary of the Passaic River, approximately 35 mi (56 km) long, in northern New Jersey in the United States. The upper course of the river flows through a wooded mountainous valley, whereas the lower course flows through the populated New Jersey suburbs and former industrial area west of New York City. It drains an area of approximately 130 sq mi (340 km²).
It rises at the eastern edge of Sussex County and within a few hundred yards enters Morris County, in the Highlands, along the northwestern slope of Green Pond Mountain south of Oak Ridge. It flows SSW, in a direct course between in the valley between the mountain ridges. Northeast of Wharton it emerges from the mountains and flows generally east in a meandering course, past Wharton, Dover (where it enters a concrete channel), Rockaway, Denville and Boonton, where it passes through the Boonton Gorge. The gorge begins with the impressive 25 foot Boonton Falls. It continues for a little over 1 mile (1.6 km) dropping around 120 feet per mile (23 m/km) through nearly continuous class 3 and 4 whitewater. On the south side of Boonton it is impounded to form the Boonton Reservoir. Downstream from the reservoir dam it flows south, through Lake Hiawatha, where the river splits and joins again. It then flows through Parsippany and into Hatfield Swamp, where it is joined by the Whippany River and then merges with the Passaic River.
Beaver brook is a stream that flows through a swamp and enters the Rockaway River in Denville.
In the 19th century the river connected to the Morris Canal near Wharton and served as an industrial transportation link for shipping coal and iron ore between Pennsylvania and New York City. The communities of Wharton, Dover, and Boonton were important iron processing towns in the early 19th century, with a large concentration of forges and mills. The significant pollution problem in the lower course of the river has been somewhat alleviated by legislation and by the nearly complete abandonment of heavy industry in the area.
The isolated upper course of the river is a popular region site for smallmouth bass fishing.
The New Jersey Fish and Game stocks the river in many sections with rainbow and brown trout. Many fisherman find enjoyment in fishing the river.
The river is shown in the movie, The Station Agent, and also appears in one episode of The Sopranos.
