Maryland Route 222 (MD 222) is a state highway in the U.S. state of Maryland. The highway runs 11.36 miles (18.28 km) from MD 7 in Perryville north to U.S. Route 1 (US 1) near Conowingo. MD 222 connects Perryville, Port Deposit, and Conowingo along its route paralleling the Susquehanna River in western Cecil County. Due to limitations in the highway in Port Deposit, including a steep hill and a low-clearance railroad bridge, trucks are directed to use MD 275, MD 276, and US 1 through Woodlawn and Rising Sun to connect Interstate 95 (I-95) with US 222 in Conowingo.

MD 222 was built as MD 268, a number presently assigned to North Street in Elkton. The state highway was paved from Perryville to Port Deposit in the late 1910s and early 1920s. MD 268 was extended north to Conowingo in the early 1930s. In 1938, MD 268 was superseded when US 222 was extended south from US 1 in Conowingo to US 40 in Perryville. US 222 was widened from Perryville to Port Deposit in the early 1940s and rebuilt around 1960. The highway was moved for the construction of I-95 interchange in the early 1960s and rebuilt south to Perryville in the late 1960s. MD 222 was established in 1972 on the portion of US 222 between MD 7 and US 40. The designation was extended from Perryville to Conowingo in 1995 when US 222 was rolled back to its former and present terminus at US 1 in Conowingo.
