Maryland Route 410 (MD 410) is a state highway in the U.S. state of Maryland. Known for most of its length as East–West Highway, the highway runs 13.92 miles (22.40 km) from MD 355 in Bethesda east to Pennsy Drive in Landover Hills. MD 410 serves as a major east–west commuter route through the inner suburbs on the north side of Washington, D.C. (hence its name), connecting the commercial districts of Bethesda, Silver Spring, and Hyattsville; in addition, the highway serves the industrial area of Landover Hills and the residential suburbs of Chevy Chase, Takoma Park, Chillum, Riverdale. and East Riverdale. The road connects many of the arterial highways and freeways that head out of Washington as well as transit hubs centered on stations of the Washington Metro in Bethesda, Silver Spring, Hyattsville, and New Carrollton, with additional connections to MARC and Amtrak.

MD 410 was originally built along mostly new alignment between Bethesda and Silver Spring in the late 1920s. The highway was extended east to Hyattsville in the mid-1930s. While the Montgomery County portion has not changed much in the ensuing decades, MD 410 has been realigned and extended multiple times within Prince George's County. These changes include an extension along existing roads further into Hyattsville in the mid-1940s, a realignment within Hyattsville in the mid-1950s, an extension through Riverdale in the late 1960s, and the final extension to Landover Hills in the early 1990s.
