Oklahoma is a state in the United States. It has 77 areas called counties. This makes Oklahoma 20th in size among U.S. states. It is 17th in the number of counties. For example, Mississippi has 82 counties, and Arkansas has 75.

When Oklahoma first became a territory, it had only seven counties. These were Logan, Cleveland, Oklahoma, Canadian, Kingfisher, Payne, and Beaver. They were first known by numbers, like "First County" or "Seventh County." Any new counties added after that were given letters of the alphabet. Later, the first seven counties were given proper names.

In 1907, Oklahoma officially became a state. At that time, the Oklahoma Constitutional Convention named all the counties. Only two new counties have been created since then. When Oklahoma became a state, all counties had smaller areas called civil townships. But a few years later, a new rule allowed counties to get rid of these townships if they voted to. By the mid-1930s, all counties in Oklahoma had decided to remove their townships.

The Oklahoma Constitution has a rule about counties. A county can be closed down if all its taxable property is worth less than $2.5 million. If this happens, a special request must be signed by one-fourth of the people living there. Then, everyone in the county would vote. If most people vote to close the county, it will join a nearby county. It would join the county with the lowest value of taxable property.

Each county in the U.S. has a special code. This is called the Federal Information Processing Standard (FIPS) code. The U.S. government uses it to identify counties. In the list below, each FIPS code links to information about that county. The area numbers in the table show only land area. They do not include any water areas.

Oklahoma's short name, or postal abbreviation, is OK. Its FIPS state code is 40.
