Maryland Route 223 (MD 223) is a state highway in the U.S. state of Maryland. The state highway runs 12.65 miles (20.36 km) from a dead end in Piscataway north to Mellwood Road in Melwood. MD 223 passes through suburban areas of southern Prince George's County, including the community of Woodyard south of Andrews Air Force Base between MD 5 in Clinton and MD 4 in Melwood. The highway was constructed from Clinton to near Piscataway in the 1920s and early 1930s. MD 223 was extended west to Livingston Road in Piscataway and east to MD 4 in the mid-1950s. MD 223's interchanges with MD 4 and MD 5 were built in the mid-1960s and early 1990s, respectively.
