A county commission (or a board of county commissioners) is a group of elected officials (county commissioners) collectively charged with administering the county government in some states of the United States. A county usually has three to five members of the county commission. In some counties within Georgia a sole commissioner holds the authority of the commission.
In parts of the United States, alternative terms such as county board of supervisors or county council may be used in lieu of, but generally synonymous to, a county commission. However, in some jurisdictions there may be distinct differences between a county commission and other similarly titled bodies. For example, a county council may differ from a county commission by containing more members or by having a council-manager form of government. In Indiana, every county, except Marion County which is consolidated with the city of Indianapolis, has both a county commission and a county council, with the county commission having administrative authority and the county council being responsible for fiscal matters.
