Clarksville is an unincorporated community in Howard County, Maryland; the second highest-earning county in the United States according to the U.S. Census Bureau. The community is named for William Clark, a farmer who owned much of the land on which the community now lies and served as a postal stop that opened on the 4th of July 1851.

Montrose and Richland Farm are listed on the National Register of Historic Places in 1973.
