Crook County is a county located in the U.S. state of Oregon. In 2000, its population was 19,182. It is named after George Crook, a U.S. Army officer who served in the American Civil War and various Indian Wars. The seat of the county is Prineville.


Forest products, agriculture, livestock raising and recreation/tourism services constitute Crook County's total economy. Agriculture is supported by the development of irrigation districts, which permits the raising of hay, grain, mint, potatoes, and seed. Range and forest lands allow grazing for a sizable livestock industry. The Ochoco National Forest's stand of ponderosa pine is the main source of lumber. As the lumber industry suffers from restrictions on log cutting, tourism and recreation are helping to strengthen the economy. Thousands of hunters, fishers, boaters, sightseers and rockhounds are annual visitors to its streams, reservoirs and the Ochoco Mountains. The Prineville Chamber of Commerce provides access to over 1,000 acres (4 km²) of mining claims to rockhounds, who can dig for free agates, limb casts, jasper and thundereggs.


The county is located in the geographic center of Oregon. It has a total area of 7,737 km² (2,987 sq mi). 7,717 km² (2,979 sq mi) of it is land and 21 km² (8 sq mi) of it (0.27%) is water. It has been reduced from its original size of 8,600 square miles by the creation of Jefferson County in 1914 and Deschutes County in 1916. The present boundaries were established in 1927.

The oldest geological formation in Oregon is in the southeastern corner of Crook County, near its boundary with Grant County. This formation is an outcropping of Devonian limestone created from a larger reef when most of Oregon was covered by water.

Access into the region at first was difficult, which discouraged settlement. The first effort to develop routes into the area was in 1862 when a supply train with cattle crossed the Scott Trail. This was also the first group of non-natives to spend the winter in central Oregon. The discovery and development of the Santiam Pass in the 1860s improved access into the area.

Crook County was formed from the southern part of Wasco County on October 24, 1882, and established Prineville as the county seat. The voters confirmed the choice of Prineville, the only incorporated town in the county, in the 1884 general election.
