The Eastside Park section of the city is generally defined as the area of the city bordered by Vreeland Avenue and East 33rd Street (both part of the "old" York Road) to the west, 20th Avenue to the south, McLean Boulevard (Route 20) to the east, and Martin Luther King, Jr. Way (Broadway) to the north.

The Eastside Park section is delineated from the Manor section of the city by Broadway, which becomes Route 4 before crossing the Passaic River into Elmwood Park (formerly East Paterson) in Bergen County.

In recent years, people have begun moving back into the neighborhood and are restoring some of the area's historic houses.

[3][4][5] The jewel of the neighborhood remains Eastside Park and the mansions that surround it.

The Eastside Park neighborhood now houses the Paterson campus of the Islamic Center of Passaic County, one of the largest Muslim communities in the United States, which serves a congregant base of over 25,000 people.
