State Route 502 (SR 502, officially known as the Battle Ground Highway) is a 6.12-mile-long (9.85 km) state highway in the U.S. state of Washington, serving the city of Battle Ground in Clark County. The highway travels due east from an interchange with Interstate 5 (I-5) north of Mount Vista through Dollars Corner and Battle Ground to an intersection with SR 503, serving as connector between Battle Ground and I-5. Prior to the 1964 highway renumbering, SR 502 was part of Secondary State Highway 1S (SSH 1S), which was established in 1937. The highway traveled south from its current western terminus until the construction of a new interchange with I-5 in 2008, part of a project to widen SR 502 and install a median barrier on the roadway.

SR 502 begins as the four-lane Battle Ground Highway at exit 11 on I-5, a partial cloverleaf interchange located north of Mount Vista, and travels due east as 219th Street, crossing Gee Creek and passing the northbound Gee Creek rest area. The four-lane highway travels east through rural Clark County and the community of Dollars Corner before it enters the city of Battle Ground, where it becomes Main Street. SR 502 crosses over Mill Creek and travels through the city, ending at an intersection with SR 503 and Main Street.
