State Road 585 (SR 585) was a 2.782-mile-long (4.477 km), north–south state highway in Tampa, Florida connecting U.S. Route 41 Business (US 41 Bus.)

The completion of the I-4/Selmon Expressway Connector provided a new corridor for traffic traveling between the two freeways, resulting in the Florida Department of Transportation relinquishing SR 585 to the city of Tampa in December 2016.

The northern terminus of SR 585 was US 92 where the roadway continued north as 22nd Street.

SR 585 was to the east side of Downtown Tampa but remained within the city limits throughout its entire course.

The entire route is in Tampa, Hillsborough County.
