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.^[1] It was formerly part of U.S. Route 40, a former cross-country highway connecting downtown Sacramento to Roseville and points beyond. To a lesser extent, most of Auburn Boulevard was also part of U.S. Route 99E, an eastern branch of the former U.S. Route 99, now succeeded by State Route 99.

Auburn Boulevard was also known as part of both the Lincoln Highway and the Victory Highway during the period from 1915 until the late 1920s when the custom of named highways gave way to the convention of numbered highways in the U.S. Highway System. It served as US 40 in North Sacramento until the completion of the North Sacramento Freeway (present day State Route 160 and Business 80/Capital City Freeway) in the early 1950s, and that section was redesignated US 40 Business until the mid-1960s. The section of Auburn Boulevard east of Howe Avenue continued to carry US 40 until the completion of the Roseville Freeway (also present day Business 80/Capital City Freeway) in 1959.

US 40 was ultimately decommissioned in 1964 when California renumbered most of its highways. Interstate 80 in California is the successor to US 40.

For most of its length, Auburn Boulevard is a four-lane roadway carrying local and regional traffic. 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. Many of these establishments have been closed or transferred, however many are still open to some capacity.
