State Route 209 (SR 209) was a state highway in the U.S. state of California, connecting Cabrillo National Monument with the interchange of Interstate 5 (I-5) and I-8 in San Diego, passing through the neighborhoods of Point Loma. The majority of the route was along Rosecrans Street; it also included Cañon Street and Catalina Boulevard leading to the tip of Point Loma.

The Rosecrans Street portion of SR 209 corresponded to the original routing of the historic La Playa Trail. Rosecrans Street was paved in the late 19th century through the community of Roseville, and was added to the state highway system in 1933 as Route 12. SR 209 was designated in the 1964 state highway renumbering, and a full interchange with I-5 and I-8 was completed in 1969. The designation was removed from the state highway system in 2003 and responsibility for the road was transferred to the city of San Diego.
