Maryland Route 144 (MD 144) is a collection of state highways in the U.S. state of Maryland. These highways are sections of old alignment of U.S. Route 40 (US 40) between Cumberland and Baltimore. Along with US 40 Scenic, US 40 Alternate, and a few sections of county-maintained highway, MD 144 is assigned to what was once the main highway between the two cities, connecting those endpoints with Hancock, Hagerstown, Frederick, New Market, Mount Airy, Ellicott City, and Catonsville. MD 144 has seven disjoint sections of mainline highway that pass through the Appalachian Mountains in Allegany and Washington counties and the rolling Piedmont of Frederick, Carroll, Howard, and Baltimore counties.
