State Route 142 (SR 142) is a state highway in southern Washington. It is located entirely within Klickitat County and runs east–west for 35 miles (56 km) from Lyle to Goldendale. The highway terminates at SR 14 in Lyle and U.S. Route 97 (US 97) in Goldendale.

The highway follows the Klickitat River and an abandoned railroad grade that was built in 1903 and converted into a recreational trail in the 1990s. The county government built a road through the Klickitat River Canyon in 1934 and transferred it to state control in the 1960s, when it was designated as Secondary State Highway 8E (SSH 8E). The highway was initially renumbered to SR 122, but instead became SR 142 in 1967.
