Garrett County (/ɡərɛt/) is the westernmost county of the U.S. state of Maryland completely within the Appalachian Mountains. As of the 2020 census, the population was 28,806, making it the third-least populous county in Maryland. Its county seat is Oakland. The county was named for John Work Garrett (1820–1884), president of the Baltimore and Ohio Railroad. Created from Allegany County in 1872, it was the last county to be formed in the state. The county is part of the Western Maryland region of the state. Garrett County is bordered by four West Virginia counties and to the north the Maryland–Pennsylvania boundary known as the Mason–Dixon line. The eastern border with Allegany County was defined by the Bauer Report, submitted to Governor Lloyd Lowndes, Jr. on November 9, 1898. The Potomac River and State of West Virginia lie to the south and west.

Garrett County lies in the Allegheny Mountains, which here form the western flank of the Appalachian Mountain Range. Hoye-Crest, a summit along Backbone Mountain, is the highest point in Maryland at an elevation of 3,360 feet (1,020 m).

The Eastern Continental Divide runs along portions of Backbone Mountain. The western part of the county, drained by the Youghiogheny River, is the only part of Maryland within the Mississippi River drainage basin. All other parts of the county are in the Chesapeake Bay basin.

The National Register of Historic Places listings in Garrett County, Maryland has 20 National Register of Historic Places properties and districts, including Casselman Bridge, National Road a National Historic Landmark. Garrett County is part of Maryland's 6th congressional district. The extreme south of the county lies within the United States National Radio Quiet Zone.

In the early 20th century, the railroad and tourism started to decline. Coal mining and timber production continued at a much slower pace. Today, tourism has made a dramatic rebound in the county with logging and farming making up the greatest part of the economic base. Due to a cool climate and lack of any large city, Garrett County has remained a sparsely populated rural area.

According to the U.S. Census Bureau, the county has a total area of 656 square miles (1,700 km), of which 647 square miles (1,680 km) is land and 8.6 square miles (22 km) (1.3%) is water. It is the second-largest county in Maryland by land area.

Garrett County is located entirely within the highland zone of the Appalachian Mountains known variously as the Allegheny Mountains, the Allegheny Plateau, and the Appalachian Plateau. The county's highest elevations are located along four flat-topped ridges and range to a height of 3,360 feet (1,020 m) at Hoye-Crest along Backbone Mountain, the highest point in the state of Maryland. As is typical in the Allegheny region, broad flats generally lie below the ridge crests at elevations of approximately 500 feet (150 m). River valleys are generally narrow and deep, with ravines typically 1,000 to 1,800 feet (550 m) below surrounding peaks.

The county contains over 76,000 acres (310 km) of parks, lakes, and publicly accessible forestland. It is drained by two river systems, the Potomac and the Youghiogheny. The Savage River, a tributary of the Potomac, drains about a third of the county. The Casselman River, a tributary of the Youghiogheny, flows north from the county's central section into Pennsylvania. The Youghiogheny itself drains the westernmost area of the county and flows north into Pennsylvania, where it empties into the Monongahela River at McKeesport, just south of Pittsburgh.

The Glades' 601 acres (2.43 km) is of great scientific interest because it is an ombrotrophic system (fed solely by rainwater) with peat layers up to 9 feet (2.7 m) thick, and is one of the oldest examples of mountain peatland in the Appalachians.

On the western edge of the Savage River State Forest along Maryland Route 495 lies Bittinger, Maryland, which is named after Henry Bittinger, who first settled in the area and who was joined by other German settlers moving in and taking up the fertile farmland. On the eastern edge of Bittinger is one of the largest glades area of Garrett County. Geographically, this is an area that seems to have been affected by the last great ice sheet of North America. Two miles southeast of Bittinger, there is a large deposit of peat moss.

In the Casselman River valley, 1-mile (1.6 km) south of Grantsville, Maryland and beside Maryland Route 495, one can see remains of geological evidence about the last great ice sheet over North America. A series of low mounds can be seen in the fields on the west side of Maryland Route 495 that are "loess" (wind-blown) material. Apparently, these are the only ones still visible in the northern part of Garrett County.

The mounds were formed when a glacier lake existed in the Casselman valley, and the ice around the edges of the frozen lake melted. Wind blew fine grains of earth into the water around the edges where it sank to the bottom, and the mounds were the result of the deposit of this wind-blown material.

The county is governed by an elected three-member Board of County Commissioners, whose members serve four-year terms and must live in the district they represent. The Board is the traditional form of county government in Maryland. It may exercise only those powers conferred by the General Assembly of Maryland, and even those powers are narrowly construed.

Garrett County is administered under a line organizational method, with the County Administrator responsible for the general administration of County Government. The administration of the county is centralized with the County Administrator responsible for overseeing the financial planning, annual budget process, personnel management, and direction and management of operations within the organization.

Although since the Civil War Maryland has been a Democratic-leaning state, Garrett County, owing to its history of German settlement from north of the Mason–Dixon line, plus strong pre-war Unionism resulting from virtual absence of slaves, has always been strongly Republican. Since it was created in 1872, Garrett is one of forty counties across the nation (chiefly Unionist strongholds in antebellum slave states) to have never voted for a Democratic presidential candidate. Compared with neighbouring and closely allied Grant County, West Virginia, Garrett has not shown quite the same levels of Republican support – Lyndon Johnson did get within 109 votes of Barry Goldwater in 1964 – but as with Grant County, the only occasion Garrett County has not been carried by the official Republican nominee occurred in 1912 when a major split in the Republican Party allowed "Bull Moose Party" nominee and former President Theodore Roosevelt to claim the county. Since 1996, no Democratic presidential nominee has won even 30% of the county's vote, and not since 2010 has Garrett County voted Democratic in any statewide election.

Owing to its strong Republican lean, Garrett County sometimes votes against ballot measures that the rest of the state approves by large margins. In 2022, for example, Garrett County was the only county in the state to vote against legalizing recreational cannabis via Question 4.

Garrett County is represented in the U.S. House of Representatives by the 6th congressional district, which includes part of northwestern metro DC. The district is currently represented by Democrat David Trone.

Garrett County produces natural gas, the only county in the state to do so. Much of the economic activity in the area centers around tourism. In the winter, the Wisp ski resort in Oakland and New Germany State Park's cross-country skiing trail are frequent destinations, and Deep Creek Lake sees much activity in the summer. The state parks in the county are frequented year-round. During the Covid-19 Pandemic, tourism boomed as many people from Washington, DC, Baltimore, and Pittsburgh wanted to get away from the city.

Garrett County Airport (2G4) is a general aviation airport surrounded by the mountains of Western Maryland. The airport enhances the region's tourist industry and provides emergency air service evacuation and landing facilities for general aviation.

Garrett County is part of the Pittsburgh, Pennsylvania television market. KDKA-TV and WTAE-TV in Pittsburgh, Pennsylvania, and WJAC-TV in Johnstown, Pennsylvania serves Oakland, the county seat. Oakland also has an educational television station (by way of PBS member station WGPT, part of state-wide Maryland Public Television; it is also served by Pittsburgh-based member station WQED).

It has a weekly newspaper, the Garrett County Republican, which was purchased by NCWV Media in 2017.

Annual events include the Autumn Glory Festival, the Scottish Highland Festival, and the Garrett County Agricultural Fair.
