State Road 423 (SR 423), known for most of its length as John Young Parkway, and Lee Road east of Orange Blossom Trail, is a four- and six-lane surface road in the U.S. state of Florida. SR 423 runs from SR 408 north to U.S. Routes 17/92 (US 17/92) just east of Interstate 4 (I-4).

SR 423 and its southern components serve as an alternate to the parallel Orange Blossom Trail. The road is named after John Young, a NASA astronaut and one of twelve men to walk on the Moon, who was from the Orlando area.^[3]
