State Route 19 (SR 19), also known as Lakewood Boulevard and Rosemead Boulevard, is a state highway in the Los Angeles area of the U.S. state of California. The route is a north–south four-to-six lane suburban roadway, lying between the Long Beach Freeway (I-710) and San Gabriel River Freeway (I-605), and connecting the eastern parts of Long Beach and Pasadena via the Whittier Narrows. Since 1998, several pieces have been relinquished to local governments, and more transfers are authorized by state law. The portion of SR 19 north of the Whittier Narrows is officially State Route 164, once planned to be upgraded as the Rio Hondo Freeway, but has always been signed as part of SR 19.

Lakewood Boulevard (no longer SR 19 in Long Beach) begins at the Long Beach Traffic Circle, where State Route 1 (Pacific Coast Highway) heads west and southeast, and Los Coyotes Diagonal heads northeast. It heads north past Interstate 405, passing under a runway of the Long Beach Airport. (The part through the airport has been relocated to the east; parts of the old alignment remain as airport service roads.) Lakewood Boulevard (no longer SR 19 in Lakewood) passes to the west of Lakewood Center Mall before passing through the neighborhood of Mayfair.
