County Route 511, abbreviated CR 511, is a county highway in the U.S. state of New Jersey. The highway extends 37.44 miles (60.25 kilometers) from Columbia Avenue (CR 510) in Morris Township to the New York state line in West Milford.

CR 511 intersects Interstate 287 at Exit 40 in Parsippany-Troy Hills Township.

CR 511 begins at an intersection with CR 510 in Morris Township, Morris County, heading northeast on four-lane undivided Whippany Road. The route passes business parks before running between business parks to the northwest and homes to the southeast. The road widens into a divided highway and comes to the CR 650 intersection, where it forms the border between Hanover Township to the northwest and Morris Township to the southeast as it interchanges with the Route 24 freeway. CR 511 turns east into residential neighborhoods as an undivided road, becoming a divided highway again briefly as it comes to the CR 623 junction. At this point, the route fully enters Hanover Township and heads northeast past more homes, alternating between a four-lane divided and undivided road. CR 511 splits from Whippany Road by turning northwest onto two-lane Parsippany Road, with CR 622 continuing northeast along Whippany Road. The road turns north and passes over the Whippany River and crosses the Morristown and Erie Railway at-grade before intersecting CR 622 Alternate and coming to an interchange with Route 10. Past this interchange, the road runs through wooded neighborhoods before entering Parsippany-Troy Hills. At this point, CR 511 widens to four lanes and passes business parks, briefly widening into a divided highway. The route narrows into a two-lane undivided road as it interchanges with I-287 and passes through residential and commercial areas a short distance to the east of Lake Parsippany. CR 511 widens back to four lanes passes more business parks prior to coming to a bridge over I-80 and reaching an intersection with US 202 and CR 630, where CR 511 forms a concurrency with US 202.
