Osage County, Oklahoma: Administration, Jail, Clerk of Court, Sheriff’s Office

Osage County isn’t just Oklahoma’s largest county by land area — its boundaries are exactly coextensive with the Osage Nation Reservation, a federally recognized tribal reservation established by 19th-century treaty when the Osage people relocated from Kansas. That overlap between county and reservation jurisdiction genuinely shapes how law enforcement operates here, in ways that don’t apply to most counties in this series. Home to Pawhuska and roughly 47,000 residents spread across more than 2,300 square miles, Osage County runs Oklahoma’s standard county government structure layered onto this distinctive tribal-jurisdictional landscape. Here’s how it works.

Osage County Quick Facts

A County Coextensive With a Sovereign Nation

Osage County was created in 1907 when Oklahoma was admitted as a state, and its boundaries exactly match the Osage Nation Reservation, established by treaty in the 19th century when the Osage relocated there from Kansas following displacement dating back to the Beaver Wars of the 17th century. The county seat, Pawhuska, is one of the first three towns established in the county and remains a hub of Osage history and culture.

This dual jurisdiction — a state county government operating on land that’s also a federally recognized tribal reservation — means law enforcement, court jurisdiction, and certain civil matters can involve coordination between county authorities and the Osage Nation’s own government, depending on the specific circumstances, parties involved, and location of an incident. Anyone with a legal matter connecting to tribal land or Osage Nation members should confirm which jurisdiction applies to their specific situation.

A few structural basics:

• The Board of County Commissioners — currently Anthony Hudson (District 1), Steve Talburt (District 2), and Chad Ray (District 3) — handles county administration from Pawhuska
• The Sheriff, County Clerk (Christina Talburt), and County Assessor (Ed Quinton) are separately elected officials
• Osage County’s 2024 elections included Clerk, Sheriff, County Commission, and Court Clerk races, with the next full cycle following Oklahoma’s standard schedule

The Sheriff’s Office

Sheriff Bart Perrier leads the Osage County Sheriff’s Office, headquartered at 900 St. Paul Avenue in Pawhuska. Perrier’s own career path through the department reflects a genuinely specialized law enforcement background — he graduated from the Oklahoma Department of Public Police K-9 Patrol and Narcotics Detection Handlers Academy, was promoted to field Sergeant in 2005, graduated from the CLEET Criminal Investigation Academy in 2006, and was appointed Reserve Deputy Coordinator in 2007, responsible for employing, directing, and training reserve deputies across the county before eventually becoming sheriff.

The Sheriff’s Office’s core responsibilities include:

• Law enforcement and public safety, including emergency response and criminal investigations
• County Jail operations, overseeing detention and inmate care
• Civil process service, including offender registration
• Background check processing

Given the county’s enormous geographic footprint — the largest in Oklahoma by area, spanning 2,246 square miles — deputies cover substantially more ground per officer than in denser counties, a genuine operational challenge unique to Osage County’s scale.

Contacting the Sheriff’s Office

The Sheriff’s Office maintains several distinct contact points depending on your need:

• Main line: (918) 287-3535, also reachable toll-free at (888) 287-3150
• Fax: (918) 287-6011
• Civil Services, Offender Registration, and Background Checks all route through the main office
• For emergencies, always dial 911 rather than the main line

For anyone trying to locate someone in the county jail, contact the Sheriff’s Office directly for current booking and custody status information, since online resources may vary in completeness for a county of this size and rural character.

The County Clerk and Public Engagement

Christina Talburt serves as Osage County Clerk, maintaining official county records. The Sheriff’s Office has also been notably active in community outreach — recent events included distributing more than 1,100 backpacks with school supplies, free haircuts, free sports physicals, a clothing resource room, and hundreds of hot dogs served at a community event, reflecting a visible community-first engagement approach beyond standard law enforcement duties.

A few practical points:

• The Osage County Courthouse, at 600 Grandview Ave in Pawhuska, houses commissioner offices, the Assessor, and other county functions
• Case records for court matters can generally be checked through Oklahoma’s statewide OSCN.net system, though not every county is fully searchable through it — confirm Osage County’s coverage before relying on it exclusively
• Self-help resources exist for people representing themselves in court, though staff cannot provide legal advice

Before You Visit

• Bring valid, government-issued photo ID to any county building, courthouse, or the jail
• If your matter involves Osage Nation tribal jurisdiction, confirm with both county and tribal authorities which applies to your specific situation before proceeding
• Given the county’s large geographic size, confirm travel time and which office serves your specific area before making a trip
• Call the Sheriff’s Office’s toll-free line, (888) 287-3150, if you’re contacting from outside the local area code

Frequently Asked Questions

Q1. Why is Osage County the same size and shape as a tribal reservation?

Osage County’s boundaries were set in 1907 to exactly match the Osage Nation Reservation, established by 19th-century treaty when the Osage people relocated there from Kansas. This means county and tribal jurisdiction can overlap depending on the specific matter and parties involved — confirm which applies to your particular situation.

Q2. How do I find out if someone is in the Osage County Jail?

Contact the Sheriff’s Office directly at (918) 287-3535 or toll-free at (888) 287-3150 for current booking and custody status information.

Q3. Does the Osage County Sheriff’s Office handle matters involving Osage Nation tribal members or tribal land?

Jurisdiction can depend on the specific circumstances, including where an incident occurred and who’s involved. For matters connecting to tribal land or Osage Nation citizens, confirm with both county and Osage Nation authorities which jurisdiction applies before assuming county process alone covers your situation.

Q4. Given Osage County’s large size, how do I know which county office serves my area?

As Oklahoma’s largest county by land area at 2,246 square miles, travel times between communities can be significant. Confirm the specific office location and hours for your matter — whether the Courthouse in Pawhuska or the Sheriff’s Office — before making a trip, since the county’s rural geography means services aren’t always centrally located near every resident.
