The Patuxent River is a tributary of the Chesapeake Bay in the state of Maryland. There are three main river drainages for central Maryland: the Potomac River to the west passing through Washington D.C., the Patapsco River to the northeast passing through Baltimore, and the Patuxent River between the two. The 957 square mile Patuxent watershed had a rapidly growing population of 590,769 in 2000.

The river source, 113 miles from the Chesapeake, is in the hills of the Maryland Piedmont near the intersection of four counties - Howard, Frederick, Montgomery and Carroll. Flowing in a generally southeastward direction, the Patuxent crosses the urbanized corridor between Baltimore and Washington, D.C. and opens up into a navigable tidal estuary near the colonial town of Queen Anne in Prince George's County, Maryland, just southeast of Bowie, Maryland, finding the Chesapeake Bay 50 miles later. The 50 mile long tidal estuary is never wider than 2.3 miles.

The Patuxent River is the longest river to be located entirely within the state of Maryland. It marks the boundary between Montgomery, Prince George's, Charles and St. Mary's Counties on the west and Howard, Anne Arundel, and Calvert Counties on the east. The Chesapeake estuary's deepest point, 130 feet below sea level, is in the lower Patuxent.

The Little Patuxent River, the Middle Patuxent River, and the Western Branch (in Prince Georges County) are the three largest tributaries. The Middle Patuxent flows into the Little Patuxent just upstream from the historic Savage Mill in Savage, Maryland. The Little Patuxent then joins the Patuxent just northeast of Bowie, Maryland. The Middle Patuxent flows through the middle of Howard County, while the Little Patuxent flows through northeast and southeast Howard County and western Anne Arundel County.

The Patuxent River was first named ("Pawtuxunt") on the detailed map resulting from the 1608 voyage upriver by Jamestown, Virginia settler John Smith. Captain Smith probably got as far as the Lyons Creek vicinity, 38 miles from the Chesapeake on what is now the Anne Arundel - Calvert County boundary. This was most likely the second visit by Europeans to the Patuxent, as in June 1588 a small Spanish expedition under Vincente Gonzales most likely anchored for the night in the Patuxent mouth.

By the mid 1600's, colonists spread upriver to Mt. Calvert and Billingsley Point, two colonial mansions 41 miles upriver from the Chesapeake that are today part of Patuxent River Park. By the early 1700's, the Snowden iron ore furnace just southeast of Laurel, Maryland was shipping "pig iron" downriver from the current vicinity of the 1783 Snowden Montpelier Mansion, also part of Patuxent River Park. The Patuxent was plied by regular steamship service, mostly from the Weems Line, from the 1820's to the 1920's, replacing the schooners and sailing packets that had for the previous centuries served the river's many landings and docks along the 50 mile navigable reach.

Tobacco farming dominated the Patuxent's economy for the two centuries following settlement, with about sixty per cent of Maryland's tobacco coming from the Patuxent valley by the late 1700's. In 1814, Commodore Joshua Barney and his Maryland flotilla were trapped in the Patuxent by the British fleet under Admiral Sir George Cochburn. To keep them from British hands, Barney's men ignited the magazines of his ships in the four mile stretch above Pig Point (42 miles upriver from the Chesapeake and named after Snowden's "pig iron"). The British launched their attack on Washington, D.C. from their boats along the Patuxent at Benedict, 20 miles from the Chesapeake, Nottingham, 36 miles upriver, and the Pig Point-Upper Marlboro, Maryland vicinity in August, 1814.

Destruction of the plantations by the British and of the soil by centuries of tobacco farming brought the mid and lower Patuxent valley into a period of decline that would last until the 1930's, when there were fewer residents in the Patuxent's Calvert County than there were in the 1840's, and only a few hundreds more than in the first Calvert County census in 1790.

The 20th century saw the construction of two major dams on the Patuxent River and thus two reservoirs. These reservoirs provide drinking water for millions in central Maryland and are owned and operated by the WSSC. The Triadelphia Reservoir was formed by the upper dam, Brighton Dam. The lower dam and its associated reservior are both called Rocky Gorge, though the reservoir is also called Duckett Reservoir. Both reservoirs lie along the Howard and Montgomery county border, where a relatively deep and narrow valley exists in the otherwise rolling Piedmont terrain.

The Middle and Little Patuxent watersheds include nearly all of Columbia, Maryland including its downtown urban Lake Kittamaqundi and Wilde Lake. Columbia is a large planned community in Howard County that opened in 1967 and contains a downtown road called Little Patuxent Parkway. It was the largely unchecked erosion from this late 1960's and 1970's building spree that contributed the bulk of the Patuxent River's highest and most damaging sediment, siltation, and pollution levels to date downstream. This in turn led to a nearly complete destruction of a once thriving seafood industry along brackish portion of the river.

The river's best known environmentalist, Bernie Fowler, as an early 1970's Calvert County Commissioner, led the way in a lawsuit filed by downriver Charles, Calvert and St. Mary's counties against upriver counties. The lawsuit forced the state, the upriver counties, and the U.S. Environmental Protection Agency to enact pollution control measures. The 1985 total of 200,000 tons of sediment reaching the Chesapeake annually was reduced to 130,000 by 2004. The Patuxent is a rarity among Chesapeake watersheds in that most of its harmful phosphorous and nitrogen nutrient overloads come from its ever-increasing areas of urban runoff, and less from its other two largest contributors, point sources (industrial, sewage, etc.) and the declining agricultural areas.

Over the past fifty years, nationally-recognized land preservation efforts in this part of Maryland have saved tens of thousands of acres from the Baltimore-Washington bedroom community sprawl. The southern half of the U.S. Army's Ft. Meade was added to the Patuxent Wildlife Research Center which at 12,300 acres is the second largest contiguous public park-refuge within 30 miles of either Washington or Baltimore. It is located precisely midway between these two huge metropolitan area. The 8300 contiguous public acres centered on Jug Bay, 40 miles upriver from the Chesapeake, form the fifth largest such Baltimore-DC preserve and largest tidewater one, and the 6600 acre Patuxent River State Park in the uppermost part of the basin is the seventh largest.

Including boating on the main river and the reservoirs, the impact that recreation in natural settings now has on the river's economy is obvious. The Patuxent Naval Air Station at the mouth of the river has continued to grow over past decades, providing along with tourism the main economic engine of the lower river valley which includes the popular boating center of Solomons, Maryland.
