State Road 338 (NM 338) is a 24.440 mi state highway in the US state of New Mexico. NM 338's southern terminus is in Animas where it continues south as Route C001 and the northern terminus is northeast of Road Forks at Interstate 10 (I-10). NM 338 and NM 9 are the only two remaining state highways to form a concurrency after the 1988 renumbering.
