Marshall County is a county located on the south-central border of Oklahoma. As of the 2020 census, the population was 15,312.^[1] Its county seat is Madill.^[2] The county was created at statehood in 1907 from the former Pickens County of the Chickasaw Nation. It was named to honor the maiden name of the mother of George Henshaw, a member of the 1906 Oklahoma Constitutional Convention.^[3] The county and its cities are part of the Texoma region.

The area covered by Marshall County was part of the territory set aside by the U.S. government for resettlement of the Choctaw tribe and the closely related Chickasaw tribe from their lands in the southeastern United States. The Chickasaws began relocating to this area in 1837. The U.S. Army built Fort Washita in 1842 to protect the new arrivals from raids by other tribes. In 1857, the Chickasaw Nation formally separated from the Choctaw Nation. This area became part of Pickens County^[4] in the Chickasaw Nation.^[3]

Railroads came to the present-day Marshall County in 1901, when St. Louis, Oklahoma, and Southern Railway (acquired shortly after by the St. Louis and San Francisco Railway), known as the "Frisco," constructed a north-south line. The following year, the St. Louis, San Francisco and New Orleans Railroad (formerly the Arkansas and Choctaw Railway) laid tracks from east to west through the area. This line was sold to the Frisco in 1907. The State of Oklahoma relocated part of this line in 1941 to make way for the creation of Lake Texoma.^[3]

According to the U.S. Census Bureau, the county has a total area of 427 square miles (1,110 km²), of which 371 square miles (960 km²) is land and 56 square miles (150 km²) (13%) is water.^[5] It is the smallest county in Oklahoma by land area and the third-smallest by total area. The Red River drains the county and forms the county's southern boundary. Completion of the Denison Dam in 1942 created Lake Texoma, which inundated part of Marshall County's land area and formed the current southern boundary and the eastern boundary of the county as well.^[3]

During the 19th century, the county's economy was based on agriculture and ranching. Cotton and corn were the most dominant crops. By 1934, oats had become the third-largest crop. After the creation of Lake Texoma, cotton acreage had dropped to about 10 percent of its 1934 level, corn had fallen to less than 2 percent, while peanuts had become the third largest crop. By 2001, wheat had become the largest crop, followed by rye, oats, and peanuts.^[3]

Oil and gas production began soon after the county was formed at statehood. Pure Oil Company built an oil camp in 1940 with 43 houses and a 35-bed bunkhouse. Pure closed the camp in 1959 after a 1957 tornado had severely damaged it. At the turn of the 21st century, oil production was about 10 percent of the 1975 quantity, while gas production was about 68 percent of the 1975 quantity.^[3]

Other significant business sectors are wood products, manufacturing (especially livestock trailers), and tourism.^[3]
