State Road 51 (SR 51) is a north–south state highway in north Florida. Its northern terminus is along the overlap of US 41 and US 129.

Adams Bridge carries it across the Suwannee River three miles (5 km) north of Mayo.
County Road 51 runs north from US 41/129 and SR 6 in Jasper to the Georgia border.
