Route 10 is a 23.5 mi (37.82 km) state highway in the northern part of the U.S. state of New Jersey. It runs from an intersection of US 46 in Roxbury, Morris County, east to Prospect Avenue / Mt Pleasant Avenue (CR 577 / CR 677) in West Orange, Essex County. Route 10 is a major route through northern New Jersey that runs through Ledgewood, East Hanover, and Livingston. It is a four-lane highway for most of its length with the exception of the easternmost part of the route. Route 10 features intersections and interchanges with many major roads including Route 53 and US 202 in Morris Plains and I-287 in Hanover.

Route 10 was designated in 1927 to run from Jersey City to Dover, following the former Newark and Mount Pleasant Turnpike west of Newark. The route continued east from its present-day routing on current County Route 577, Park Avenue, CR 508, and Route 7 to end at US 1/9 at the Tonnele Circle. An alignment of Route 10 farther to the north of its current alignment in Essex County was proposed in 1952; however, it was never constructed with the route being designated to its present alignment a year later. Since 1953, Route 10 has seen improvements that eliminated the Ledgewood Circle at the western terminus in 1998 and improved safety along the portion of the route in Hanover and East Hanover townships in the mid-2000s.
