New York State Route 304 (NY 304), also known as "Rockland County Clerk Paul Piperato Memorial Highway",^[3] as well as Pearl Street for its first half a mile and Main Street for other parts, is a north–south state highway located in central Rockland County, New York, in the United States. The 10.38-mile (16.70 km) route begins at the New Jersey–New York border in Pearl River and ends at an intersection with U.S. Route 9W (US 9W) in the community of Congers. The route is a main route through Rockland County, intersecting NY 59 and indirectly connecting to the New York State Thruway and the Palisades Interstate Parkway (PIP) in Nanuet. NY 304 has three distinct sections: a freeway that extends from Pearl River to Nanuet, a surface section between Nanuet and New City, and an expressway linking New City to Haverstraw.

NY 304 was assigned in 1930, originally following a series of at-grade roads that loosely parallel its modern alignment between Pearl River and Haverstraw. Concerns over the route's ability to handle a projected 40,000 vehicles per day in 1980 led to the construction of new highways south of Nanuet and north of New City in the mid-1960s. Most of NY 304's old alignment through these areas is now maintained by Rockland County as part of several county routes.
