Oregon Route 334 (OR 334) is an Oregon state highway running from OR 37 near Myrick to OR 11 near Athena. OR 334 is known as the Athena-Holdman Highway No. 334 (see Oregon highways and routes). It is 18.12 miles (29.16 km) long and runs east–west, entirely within Umatilla County.

OR 334 was established in 2003 as part of Oregon's project to assign route numbers to highways that previously were not assigned, and, as of October 2020, was unsigned.

Three miles east of Myrick, OR 334 overlaps OR 335 for 1.13 miles (1.82 km), heading north. After OR 335 turns north toward Helix, OR 334 then continues east through Athena, ending at an intersection with OR 11 approximately one mile east of Athena.^[1][2]
