NJ Transit Bus Operations is the bus division of NJ Transit, providing local and commuter bus service throughout New Jersey and adjacent areas of New York State (Manhattan in New York City, Rockland County, and Orange County) and Pennsylvania (Philadelphia and the Lehigh Valley).

NJ Transit Bus Operations came into being the following year, when it acquired Transport of New Jersey from PSE&G.

[4] Other purchases and buyouts in the 1980s expanded the bus division of NJ Transit, including the assumption of service for Somerset Bus Company in 1982 and the acquisition of the Atlantic City Transportation Company in 1987.

[5] In 1992 NJ Transit Mercer, Inc., which was the successor to the former "Mercer Metro" operation in the Trenton and Princeton areas, was folded into NJ Transit Bus Operations.

[10] In most cases, routes retain the same numbers they had under the Public Service/Transport of New Jersey umbrella.
