Oklahoma’s Largest County

At the Osage County Sheriff’s Office, our mission is to be the foundation on which everyone in Osage County may thrive, by strengthening public trust and ensuring safe, secure environments through quality, professional law enforcement.

Osage County is the largest county by area in the state of Oklahoma. Created in 1907 when Oklahoma was admitted as a state, the county is named for and is home to the federally recognized Osage Nation. The county is coextensive with the Osage Nation Reservation, established by treaty in the 19th century when the Osage relocated there from Kansas. The county seat is in Pawhuska, one of the first three towns established in the county. The total population of the county as of 2020 was 45,818.

According to the U.S. Census Bureau, the county has a total area of 2,304 square miles (5,970 km2), of which 2,246 square miles (5,820 km2) is land and 58 square miles (150 km2) (2.5%) is water. Most of the county is in the Osage Plains, and consists of open prairie. The eastern part of the county contains the Osage Hills, an extension of the Flint Hills in Kansas. Tallgrass Prairie Preserve is north of Pawhuska.
