State Route 142 (SR 142), also known as Carbon Canyon Road for most of its length, is a state highway in the U.S. state of California that connects Brea in Orange County with Chino Hills in San Bernardino County. The eastern portion of the route is known as Chino Hills Parkway.

Running from State Route 90, Imperial Highway, in Brea to State Route 71 in Chino Hills, SR 142 is a popular shortcut from the business centers of Brea and surrounding Orange County to the Inland Empire. The road has multiple tight curves, so travel is not recommended for long vehicles, such as big rigs.
