Frederick County is a county located in Maryland, United States. It's a busy place with a growing population. As of the 2020 U.S. census, about 271,717 people lived here. The main city and county seat is Frederick. This county is part of the larger Capital region of the state.

Since the 1980s, many people have moved to Frederick County. It shares borders with Pennsylvania to the north and Virginia to the southwest. It's also home to Catoctin Mountain Park, where Camp David (a special retreat for U.S. presidents) is located, and Fort Detrick, a U.S. Army base.

What's in a Name?

The name of Frederick County and its main city, Frederick, isn't completely certain. It was likely named after either Frederick, Prince of Wales, or Frederick Calvert, 6th Baron Baltimore.

A Look Back in Time

Frederick County was created in 1748 by the Province of Maryland. It was formed from parts of what were then Prince George's County and Baltimore County.

After the United States became independent in 1776, Frederick County was divided into three parts. The western part became Washington County, named after George Washington. The southern part became Montgomery County, named after another general from the American Revolutionary War, Richard Montgomery. The northern part remained Frederick County.

Later, in 1837, a piece of Frederick County was combined with a piece of Baltimore County to form Carroll County. This new county is located east of today's Frederick County. Many historic places in the county are listed on the National Register of Historic Places.

Exploring Frederick County's Geography

According to the U.S. Census Bureau, Frederick County covers a total area of about 667 square miles. Most of this, about 660 square miles, is land, and a small part (about 7.2 square miles) is water. It's actually the largest county in Maryland when you look at its land area.

Frederick County sits right where two different land regions meet: the Piedmont Plateau Region and the Appalachian Mountains. The county has two main mountain ridges, Catoctin Mountain and South Mountain. These are like extensions of the Blue Ridge Mountains. Between these two ridges lies the Middletown Valley.

There are many interesting places to visit in the Frederick area. These include the Clustered Spires, a monument dedicated to Francis Scott Key, the National Museum of Civil War Medicine, and the battlefields of Monocacy National Battlefield and South Mountain. You can also visit the Schifferstadt Architectural Museum.
