Route 63 is a short, 3.09-mile (4.97 km) long state highway in Hudson and Bergen counties in New Jersey.

The route progresses northward, concurrent with County Route 501, from the intersection along Bergen Boulevard, passing through a large residential and commercial community, passing to the east of the Fairview Cemetery, located in Fairview.

Bergen Boulevard passes through the partial-residential/commercial community for a distance, becoming a divided highway until an intersection with Cliff Street.

At Cliff Street, the right-of-ways come back together, and the highway itself passes the Mount Moriah Cemetery near a large high-rise.

The two designated routes continue northward through the residential communities as Bergen Boulevard, entering the municipality of Palisades Park soon afterwards.
