This is an incomplete list of Oklahoma state agencies.
All agencies are within one of the three branches of the government of Oklahoma.
Pursuant to the provisions of the Executive Branch Reform Act of 1986, all executive branch agencies are organized under a Cabinet Secretary.
The executive branch of government is headed by the Governor of Oklahoma, who is assisted in managing the executive branch by Cabinet Secretaries appointed by the Governor with the consent of the Oklahoma Senate.
The Lieutenant Governor of Oklahoma serves as President of the Senate and is first in line to succeed to the Governorship in the event of a vacancy.
