State Road 513 (SR 513), also known as South Patrick Drive, is a short north–south road located along the western side of the barrier island towns of Indian Harbour Beach, Satellite Beach and South Patrick Shores in Brevard County.

The southern terminus is at an intersection with SR 518 near the eastern end of the Eau Gallie Causeway in Indian Harbour Beach.

The northern terminus is at a partial interchange with the Pineda Causeway (SR 404), just south of the southern entrance of Patrick Space Force Base.

The road starts at the intersection of the Eau Gallie Causeway (SR 518) and Riverside Drive/South Patrick Drive, with SR 518 starting north on South Patrick Drive, through a mix of commercial and residential areas, staying within a few blocks of the Banana River.

North of the intersection, SR 513 becomes more residential, with the occasional commercial development, and continues through the beach community.
