The area now known as Montgomery County was originally a part of Charles County when counties were first established in Maryland. In 1696 parts of Charles and Baltimore Counties were split off to form the new Prince George's County. In turn, in 1748, a portion of Prince George's County produced Frederick County. Montgomery County was formed in 1776 by the splitting of Frederick County. The former Frederick County was subdivided into three; the central portion remained Frederick County, while the western was named Washington County in honor of General (later President) George Washington, and the eastern part was named Montgomery County in honor of another Revolutionary War general, Richard Montgomery.

In 1791, portions of Montgomery and Prince George's County, Maryland, as well as parts of Virginia, were ceded to form the new District of Columbia. (The portions originally ceded by Virginia were returned by an act of Congress, approved July 9, 1846.)

In 1997, a portion of Prince George's County was transferred to Montgomery County so that the entire city of Takoma Park would be in a single county.
