Frederick County was created in 1748 from parts of Prince George's County and Baltimore County.

In 1776, Frederick County was divided into three parts. The westernmost portion became Washington County, named after George Washington, the easternmost portion became Montgomery County, named after another Revolutionary War general, Richard Montgomery. The central portion remained Frederick County.

In 1837 a part of Frederick County was combined with a part of Baltimore County to form Carroll County.

Frederick Town was laid out in 1745 and became the county seat of Frederick County three years later. It is uncertain which Frederick the town was named for, but the likeliest candidates are Frederick Calvert, 6th Baron Baltimore and Frederick Lewis, Prince of Wales.
