Deschutes County (/dəˈʃuːts/ də-SHOOTS) is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the population was 198,253. The county seat is Bend. The county was created in 1916 out of part of Crook County and was named for the Deschutes River, which itself was named by French-Canadian trappers of the early 19th century. It is the political and economic hub of Central Oregon. Deschutes comprises the Bend, Oregon Metropolitan Statistical Area and media market. Deschutes is Oregon's fastest-growing and most recently formed county.

French-Canadian fur trappers of the Hudson's Bay Company gave the name Rivière des Chutes (River of the Falls) to the Deschutes River, from which the county derived its name.

On December 13, 1916, Deschutes County was created from the southern part of Crook County. Bend has been the county seat since the county's formation. It was the last county in Oregon to be established.

The Shevlin-Hixon Lumber Company also operated within the Bend area processing Ponderosa pine trees.

According to the United States Census Bureau, the county has a total area of 3,055 square miles (7,910 km), of which 3,018 square miles (7,820 km) is land and 37 square miles (96 km) (1.2%) is water.

Deschutes County has traditionally fallen politically more in line with the eastern side of Oregon than the western side. However, this has shifted in recent years, due in large part to the rapid growth and urbanization within the city of Bend. By January 2021, a narrow plurality of registered voters in Deschutes County were registered with the Democratic Party. In addition, Joe Biden carried the county with 52.7% of the vote in the 2020 presidential election compared to 44.4% of the vote for Donald Trump, thereby marking the first time a Democratic Party candidate won the county since 1992 and the first time a Democratic Party candidate received a majority of the vote in the county since 1964.

In 2008, the Democratic Party won the Oregon House seat encompassing the city of Bend, becoming the only Democratic-controlled district east of the Cascades, though the Republicans retook the seat in 2010. Republicans would hold the seat for the remainder of the decade until 2020, when Democrat Jason Kropf was elected to the State House and re-elected in 2022. In 2022, the 53rd District, including Redmond, elected Democrat Emerson Levy to the Oregon House. Portions of Deschutes County also fall into the 55th, 59th and 60th House Districts, respectively held by Republicans E. Werner Reschke, Vikki Breese-Iverson and Mark Owens. Deschutes County is also divvied up between the 27th, 28th and 30th Senate Districts in the Oregon Senate, respectively represented by Republicans Tim Knopp, Dennis Linthicum and Lynn Findley.

Deschutes County is currently one of 11 counties in Oregon in which therapeutic psilocybin is legal.

During the 1990s, Deschutes County experienced the most rapid growth of any county in Oregon, largely due to the year-round availability of recreational activities, and its location as the nearest population center to much of the central Cascade Range. Beyond tourism, principal industries in the county are lumber, ranching and agriculture—chiefly potatoes. The Forest Service owns 51% of the lands within the county boundaries.

Deschutes County is the home of four destination resorts as defined by Oregon's Department of Land Conservation and Development. These resorts are major employers within the county. Three of these resorts, Sunriver, Eagle Crest, and Pronghorn, are among the county's ten largest tax payers.

The overall defining landscape of Deschutes County is primarily marked with that of lava flows. Most of the lava found in Deschutes County issued forth from Newberry Volcano located just south of Bend. Because of this, many lava tubes are located within, including the prominent Lava River Cave. As a consequence, the county is the most cave-rich in the state of Oregon, with over 500 known caves in the county. Other prominent lava flows exist too, especially those related to the Mount Bachelor Volcanic Chain which consists of Mount Bachelor as well as three smaller shield volcanos, and a series of cinder cones.

Large volcanoes serve as a backdrop to the city of Bend in Deschutes County, ranging from the prominent Three Sisters, Mount Washington, Mount Bachelor, Broken Top, Newberry, Tumalo Mountain, Maiden Peak and others. A group of geologists have discovered Smith Rock State Park is part of an ancient supervolcano called the Crooked River caldera with a rim nearly six times the diameter of Newberry Volcano's caldera. This ancient supervolcano has long gone extinct. Its crater rim is barely recognizable as remnants mark portions of Powell Buttes, Gray Butte, and the western front of the Ochoco Mountains at Barnes Butte.

On the eastern side of the county, it is mostly characterized by large buttes of much older volcanic origin. Most of these did not create any proper lava flows, or at least none that are known to exist. Some of the prominent buttes include Horse Ridge, Pine Mountain, China Hat, and several others on the county border.

Two main types of lava flows are found within the county. The most common are the pāhoehoe flows which have been partially buried by volcanic ash, tephra deposits, and dirt over tens to hundreds of thousands of years. The ʻaʻā flows are fewer but much more prominent, with the most notable being associated with Lava Butte and the Lava Cast Forest in the Newberry National Volcanic Monument.
