South Carolina Highway 223 (SC 223) is a 6.740-mile (10.847 km) primary state highway in the U.S. state of South Carolina.

It serves as a connector between Richburg and Landsford Canal State Park.

SC 223 is a two-lane rural highway that traverses from SC 9 and SC 901 north of Richburg to U.S. Route 21 (US 21) in the community of Landsford and Landsford Canal State Park.

The current SC 223 was established in 1940, connecting Richburg with US 21.

In 1948, it was briefly downgraded as a secondary road, but was resurrected a year later after the road was fully paved; changed little since.
