State Route 47 (SR 47) is a state highway in the U.S. state of California, connecting Terminal Island to the mainland in the Los Angeles area. From its south end at I-110 in San Pedro, it heads east across the Vincent Thomas Bridge to the island and the end of state maintenance. The state highway begins again at the junction with I-710 on Terminal Island, crossing the Schuyler Heim Bridge north to the mainland and the second terminus, where SR 103 begins. Signage continues along a locally maintained route, mainly Alameda Street, to the Gardena Freeway (SR 91) in Compton, and an unconstructed alignment follows the same corridor to the Santa Monica Freeway (I-10) near downtown Los Angeles.

The entire route is part of the California Freeway and Expressway System, and both constructed segments are freeways, officially known as parts of the Seaside Freeway (which continues to SR 1 via I-710) and Terminal Island Freeway (which continues to SR 1 via SR 103). However, there are several at-grade intersections along the gap on Terminal Island, and Alameda Street is a surface roadway, albeit one with few intersections, as it runs alongside the Alameda Corridor rail line.
