Oklahoma County is a county located in the central part of the U.S. state of Oklahoma. As of the 2010 census, the population was 718,633, making it the most populous county in Oklahoma. The county seat is Oklahoma City, the state capital and largest city.
Oklahoma County is at the heart of the Oklahoma City Metropolitan Statistical Area.
Oklahoma County is one of seven counties in the United States to share the same name as the state it is located in (the other six counties are Arkansas County, Hawaii County, Idaho County, Iowa County, New York County (known commonly as Manhattan), and Utah County), and the only one of the seven to contain the state capital.
Oklahoma County was originally called County Two and was one of seven counties established by the Organic Act of 1890.
County business initially took place in a building at the intersection of California Avenue and Robinson Street until the construction of the first Oklahoma County Courthouse at 520 West Main Street in the 1900s. In 1937, the county government was moved to a building at 321 Park Avenue, which now serves only as the county courthouse.

Since the second half of the 20th century, Oklahoma County has been somewhat conservative for an urban county. It swung from a 20-point victory for Harry Truman in 1948 to a 15-point victory for Dwight Eisenhower in 1952. It has gone Republican in all but one presidential election since then; it narrowly voted for Lyndon Johnson in 1964. This mirrors the growing Republican trend in Oklahoma since the end of World War II.
However, the Republican share of votes for President has decreased in every election since the 2004 election. In the 2018 Oklahoma gubernatorial election, Oklahoma County gave Democratic candidate Drew Edmondson the largest vote share of any county, with 54.2% of the vote, whereas Republican Mary Fallin won the county with 51.3% of the vote four years prior. Also, in the 2018 United States House of Representatives elections in Oklahoma, Democrat Kendra Horn received 52.3% of the vote in Oklahoma County, which was the only county in the state to vote for a Democratic House candidate.
