Route 10 is a 23.51 mi state highway in the northern part of the U.S. state of New Jersey. It runs from an intersection with U.S. Route 46 in Roxbury Township, Morris County east to County Route 577/County Route 677 (Prospect Avenue) in West Orange, Essex County. Route 10 is a major route through northern New Jersey that is lined with two shopping districts in Ledgewood and East Hanover/Livingston featuring many shopping centers and large commercial outlets. 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 with many major roads including Route 53 and U.S. Route 202 in Morris Plains and Interstate 287 in Hanover Township.

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, County Route 508, and Route 7 to end at U.S. Route 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.
