Auburn Boulevard is a major thoroughfare in Sacramento County, California, United States, and a tiny portion in Placer County, California carrying surface street traffic through the cities and communities of Sacramento, Arden-Arcade, Foothill Farms, Citrus Heights, and Roseville.

It is still known for the long chain of motels, trailer parks, restaurants, and gasoline stations that exist along its length that were built in the 20th century to accommodate the travelers of the automobile age.

Auburn Boulevard starts as a two-lane road in a fairly obscure location in the North Sacramento area of Sacramento where it meets the intersection of Manning Street and Harvard Street (the continuation of the roadway south of Manning), just below the El Camino Avenue overpass.

After a junction with Van Ness Street (which connects to El Camino Avenue), it continues northeast, paralleling the SacRT light rail's Blue Line and Union Pacific railroad tracks to the west.

After Howe Avenue, it is here that Auburn Boulevard straddles the Sacramento city limits, with the unincorporated community of Arden-Arcade to the south, acting as its northern border.

Despite running along the city limits, the road is maintained by SACDOT, Sacramento County's Public Works department.
