The Monongahela National Forest is a national forest located in the Allegheny Mountains of eastern West Virginia, US. It protects over 921,000 acres (3,727 km; 1,439 sq mi) of federally managed land within a 1,700,000 acres (6,880 km; 2,656 sq mi) proclamation boundary that includes much of the Potomac Highlands Region and portions of 10 counties.

The Monongahela National Forest includes some major landform features such as the Allegheny Front and the western portion of the Ridge-and-valley Appalachians. Within the forest boundaries lie some of the highest mountain peaks in the state, including the highest, Spruce Knob (4,863 ft). Spruce Knob is also the highest point in the Allegheny Mountains. Approximately 75 tree species are found in the forest. Almost all of the trees are a second growth forest, grown back after the land was heavily cut over around the start of the 20th century. Species for which the forest is important include red spruce (Picea rubens), balsam fir (Abies balsamea), and mountain ash (Sorbus americana).

The Monongahela National Forest includes eight U.S. Wilderness Areas and several special-use areas, notably the Spruce Knob–Seneca Rocks National Recreation Area.

The Monongahela National Forest encompasses most of the southern third of the Allegheny Mountains range (a section of the vast Appalachian Mountains range) and is entirely within the state of West Virginia. Elevations within the Monongahela National Forest range from about 900 feet (270 m) at Petersburg to 4,863 feet (1,482 m) at Spruce Knob. A rain shadow effect caused by slopes of the Allegheny Front results in 60 inches (1,500 mm) of annual precipitation on the west side and about half that on the east side.

Headwaters of six major river systems are located within the forest: Monongahela, Potomac, Greenbrier, Elk, Tygart, and Gauley. Twelve rivers are currently under study for possible inclusion in the National Wild and Scenic Rivers System.

The main administrative headquarters is located in Elkins, West Virginia. The Monongahela also includes four ranger districts. The forest includes 105 permanent employees, seasonal employees, and volunteers.

Monongahela National Forest is currently divided into four ranger districts. The Cheat-Potomac and Marlinton-White Sulphur Springs were formed by combining their namesake districts; in the merged districts, the offices for both original districts were retained.

• Cheat-Potomac Ranger District, Headquarters: Parsons, West Virginia
  • Office (former HQ, Potomac Ranger District) at Petersburg, West Virginia
• Gauley Ranger District, Headquarters: Richwood, West Virginia
• Greenbrier Ranger District, Headquarters: Bartow, West Virginia
• Marlinton-White Sulphur Springs Ranger District, Headquarters: Marlinton, West Virginia
  • Office (former HQ, White Sulphur Springs Ranger District) at White Sulphur Springs, West Virginia

The Monongahela National Forest was established following the Weeks Act passage in 1911. This act authorized the purchase of land for long-term watershed protection and natural resource management following the massive cutting of the eastern forests in the late 19th and early 20th centuries. In 1915, 7,200 acres (29 km) were acquired to begin the forest, called the "Monongahela Purchase", and on April 28, 1920, it became the "Monongahela National Forest". By the end of 1924, the Monongahela National Forest had total ownership of some 150,367 acres (609 km).

Although white-tail deer never vanished from the Monongahela National Forest, from the 1890s to the 1920s their numbers dropped substantially. In January 1930, eight deer procured from Michigan were released into the forest near Parsons. From 1937 to 1939, a total of 17 more deer were released in the Flatrock-Roaring Plains area of the Forest. These releases served as the nucleus for reestablishing the healthy breeding populations of eastern West Virginia. (By the mid-1940s, deer were so numerous in the area that crop farmers had to patrol their fields by night.)

In 1943 and 1944, as part of the West Virginia Maneuver Area, the U.S. Army used parts of the Monongahela National Forest as a practice artillery and mortar range and maneuver area before troops were sent to Europe to fight in World War II. Artillery and mortar shells shot into the area for practice are still occasionally found there today. Seneca Rocks and other area cliffs were also used for assault climbing instruction. This was the Army's only low-altitude climbing school.

The fisher (Pekania pennanti), believed to have been exterminated in the state by 1912, was reintroduced during the winter of 1969. At that time 23 fishers were translocated from New Hampshire to two sites within the boundaries of the Monongahela National Forest (at Canaan Mountain in Tucker County and Cranberry Glades in Pocahontas County).

In 1980, and again in 2005, the Monongahela National Forest was the venue for the annual counterculture Rainbow Gathering.

In 1993, the Craig Run East Fork Rockshelter and Laurel Run Rockshelter in the Gauley Ranger District were listed on the National Register of Historic Places.

In 2011 West Virginia Senator Joe Manchin requested the National Park Service study the feasibility of transferring the northern portions of Monongahela National Forest to the NPS, including the Spruce Knob–Seneca Rocks National Recreation Area, the Dolly Sods Wilderness, and the Otter Creek Wilderness. Advocates had proposed the area be designated as High Allegheny National Park and Preserve. Interconnecting public lands would become Preserve Areas, where hunting would be allowed; and adjacent private working farms and forests would be eligible for voluntary Heritage Area conservation easements. In October 2011, the National Park Service announced a Reconnaissance Survey, to be conducted from January to September 2012, to "determine whether the historic, natural, and recreational resources in the project area are 'likely' or 'unlikely' to meet congressionally required criteria for the designation of potential units of the National Park System".

Historic Civil War sites within the proposed park and preserve include the Rich Mountain Battlefield, Beverly Historic District, Cheat Summit Fort, Camp Bartow, and Camp Allegheny. The historic Blackwater Industrial Complex in Tucker County—preserving artifacts of the coal, coke and timber empire of early West Virginia entrepreneur and Senator Henry Gassaway Davis—would also be included.

In early 2012 Senator Manchin dropped his request for the study. Commentators on Manchin's approach to the proposal had noted that "the senator seemed to be in favor of a possible NPS label in the area only if there were no changes in existing land use or management practices". In February 2012, the NPS Director observed that some of Manchin's requests were incompatible with longstanding NPS policy, saying in part that "the continuation of extractive activities such as timber harvesting and oil and gas development would make the establishment of a national park infeasible".

The forest is noted for its rugged landscape, views, blueberry thickets, highland bogs and "sods", and open areas with exposed rocks. In addition to the second-growth forest trees, the wide range of botanical species found includes rhododendron, laurel on the moist west side of the Allegheny Front, and cactus and endemic shale barren species on the drier eastern slopes.

There are 230 known species of birds inhabiting the Monongahela National Forest: 159 are known to breed there, 89 are Neotropical migrants; 71 transit the forest during migration, but do not breed there, and 17 non-breeding species are Neotropical. The Brooks Bird Club (BBC) conducts an annual bird banding and survey project in the vicinity of Dolly Sods Scenic Area during migration (August – September). The forest provides habitat for 9 federally listed endangered or threatened species: 2 bird species, 2 bat species, 1 subspecies of flying squirrel, 1 salamander species, and 3 plant species. Fifty other species of rare/sensitive plants and animals also occur in the forest.

Larger animals and game species found in the forest include black bear, wild turkey, white-tailed deer, gray and fox squirrels, rabbits, snowshoe hare, woodcock, and grouse. Limited waterfowl habitat exists in certain places. Furbearers include beaver, red and gray fox, bobcat, fisher, river otter, raccoon and mink. Other hunted species include coyotes, skunks, opossums, woodchucks, crows, and weasels. There are 12 species of game (pan) fish and 60 species of nongame or forage fish. Some 90% of the trout waters of West Virginia are within the forest.

The Monongahela National Forest is a recreation destination and tourist attraction, hosting approximately 3 million visitors annually. The backwoods road and trail system is used for hiking, mountain biking, horse riding. Many miles of railroad grades are a link in the recreation use of the forest. (The longest is the Glady to Durbin West Fork Railroad Trail which is 23 miles (37 km) long.) Recreation ranges from self-reliant treks in the wildernesses and backcountry areas, to rock climbing challenges, to traditional developed-site camping. Canoeing, hunting, trapping, fishing, and wildlife viewing are also common uses.

The following are developed campgrounds in the forest:

The forest administration maintains wildlife and timber programs aimed at the responsible management of a mixed-age forest. About 81 percent of the total forest area is closed canopy forest over 60 years of age. The tree species most valuable for timber and wildlife food in the Monongahela National Forest are black cherry and oaks. The forest's commercial timber sale program averages 30 mbf (thousand board feet) of timber sold per year with a yearly average value of $7.5 million. Various cutting techniques are used, from cutting single trees to clearcutting blocks up to 25 acres (100,000 m) in size. Regeneration cuts (clear-cuts or other treatments designed to start a new timber stand) occur on approximately 1,300 acres (5.3 km) yearly out of the more than 909,000 acres (3,680 km) forest total.

Mineral resources located in the Monongahela National Forest include coal, gas, limestone, and gravel. Sheep and cattle grazing occurs on about 7,000 acres (28 km).

Receipts for timber, grazing, land uses, minerals, and recreation use averaged $4,840,466 annually between FY92 and FY96, and 25% of that (an average of $1,210,116 per year) was returned to counties that include Monongahela National Forest lands. This money is intended for use by local schools and roads. The remaining 75% each year is returned to the U.S. Treasury.
