Oregon Route 42 (OR 42) is an Oregon state highway which runs between U.S. Route 101 on the Oregon Coast, near Coos Bay, and Green, a few miles south of Roseburg on Interstate 5. OR 42 traverses the Coos Bay–Roseburg Highway No. 35 of the Oregon state highway system.^[2] The route splits at Coquille, where Oregon Route 42S heads southwest toward Bandon.

The section of Oregon Route 42 between the junction with U.S. Route 101 south of Coos Bay and the junction with Oregon Route 42S in Coquille was once a part of U.S. Route 101. When U.S. Route 101 was moved to an alignment closer to the ocean in 1961-63, Oregon Route 42 was extended along the northernmost section and Oregon Route 42S was created along the southernmost section.
