Green Country (Oklahoma) is a vernacular region in northeastern Oklahoma known for its rolling hills, forests, lakes, and urban centers centered on Tulsa, Oklahoma. The region includes a mix of metropolitan areas, small towns, and rural landscapes shaped by Native American nations, American westward expansion, and 20th‑century energy booms. Green Country is a focal point for transportation corridors, cultural institutions, and conservation areas within the Ozark Plateau, proximate to the Arkansas River and several major reservoirs.
Green Country occupies the northeastern quadrant of Oklahoma, encompassing portions of the Ozark Mountains, the Boston Mountains, and the Arkansas River Valley. Prominent hydrological features include Lake Tenkiller, Grand Lake o' the Cherokees, Oologah Lake, Eufaula Lake, and the Verdigris River. Topographical high points relate to the Ouachita Mountains foothills and the layered strata of the Mississippian and Pennsylvanian geological periods. The region contains soils derived from sandstone and limestone common to the Ozark Plateau and supports mixed oak-hickory forests similar to those in Arkansas, Missouri, and Kansas. Major urban centers and suburbs form corridors along Interstate 44, U.S. Route 69, and U.S. Route 75, with rail infrastructure connected to BNSF Railway, Union Pacific Railroad, and regional short lines.
Precontact history ties Green Country to indigenous polities including the Caddo people, Osage Nation, Quapaw people, and later relocated tribes such as the Cherokee Nation, Muscogee (Creek) Nation, Choctaw Nation, and Seminole Nation of Oklahoma. 19th‑century developments involved treaties such as the Treaty of Dancing Rabbit Creek and the Treaty of New Echota, relocations associated with the Trail of Tears, and settlement patterns altered by the Louisiana Purchase and territorial governance under the Indian Territory. The late 19th and early 20th centuries saw rail expansion by lines including the Missouri–Kansas–Texas Railroad and the Atchison, Topeka and Santa Fe Railway; urban growth centered on Tulsa, Oklahoma and Bartlesville, Oklahoma emerged alongside the discovery of oil at fields tied to companies like Marland Oil Company and later Phillips Petroleum Company. New Deal programs affected infrastructure and reservoirs built by agencies such as the U.S. Army Corps of Engineers; World War II mobilization influenced manufacturing and aviation operations including facilities linked to Douglas Aircraft Company and Boeing. Postwar eras featured civil rights activity connected to national movements such as those led by figures associated with the National Association for the Advancement of Colored People and local institutions like Langston University and University of Tulsa shaping higher education.
Green Country's economy blends energy, aerospace, manufacturing, agriculture, and services. Historic petroleum enterprises including names now associated with Marathon Petroleum Corporation, ConocoPhillips, Hess Corporation, and regional refineries anchored the energy sector; natural gas and midstream operations involve firms similar to ONEOK.

Agriculture includes production of wheat, soybeans, cattle, and poultry, with cooperative and agribusiness connections to entities like CHS Inc. and producer associations linked to the United States Department of Agriculture. Tourism, hospitality, health care, and education services concentrate in Tulsa and Muskogee and attract institutions like Saint Francis Health System and regional campuses of Oklahoma State University–Tulsa and Rogers State University. Financial and professional services include regional banks and investment firms that mirror national players such as Bank of America and Wells Fargo in footprint and function. Technology startups and creative industries cluster around incubators influenced by models from Massachusetts Institute of Technology‑affiliated accelerators and municipal development authorities.
