Maryland Route 410 (MD 410) is a state highway in the U.S. state of Maryland and known for most of its length as East–West Highway. The highway runs east to west (hence its name) for 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 northern suburbs of Washington, D.C., 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 also connects many of the arterial highways and freeways that head out of Washington. Additionally, it provides a highway connection to transit and commercial hubs centered around Washington Metro subway stations in Bethesda, Takoma Park, Hyattsville, Silver Spring, and New Carrollton–the latter two of which provide additional connections to MARC and Amtrak trains.

MD 410 was originally built along a mostly new alignment between Bethesda and Silver Spring in the late 1920s. The Montgomery County portion has not changed much in the ensuing decades. In the mid-1930s, the highway was extended east to Hyattsville in Prince George's County, where it has been realigned and extended multiple times. These changes included: 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 New Carrollton and Landover Hills in the early 1990s.
