The Association of County Commissioners of Oklahoma (ACCO) is a statewide organization bringing together 231 county commissioners across all 77 Oklahoma counties. It works to support county government and promote the health, safety, and welfare of county residents. ACCO serves as a clearinghouse for leadership training, educational programming, and services tailored to member counties.

Its resources include conferences, a calendar and county directory, legislative updates, newsletters, presentations, and guidance on county purchasing, open records, and infrastructure funding. ACCO also provides law enforcement and detention training, safety materials, sample policies, and resources related to workers’ compensation and insurance programs. Members can access information on grants and state and federal funding opportunities, as well as partnerships and purchasing resources.

Through collaboration with county officials and state leaders, ACCO represents county needs and supports improvements to local services. Its programs and events connect public officials, agencies, and vendors, helping counties share knowledge and access tools for effective government. Recent advocacy includes support for investment in Oklahoma county roads and bridges.
