State Road 10 (SR 10), also known as Atlantic Boulevard, is a major east–west state highway in the U.S. state of Florida. Mostly unsigned in favor of U.S. Highway 90, it runs from the Alabama state line (Perdido River) to Atlantic Beach. The only sections that are not signed as US 90 are north of Pensacola, where US 90 uses SR 10A and SR 10 is signed as U.S. Highway 90 Alternate, and east of south Jacksonville, where US 90 uses unsigned SR 212.
