Oklahoma County is a county located in the central part of the U.S. state of Oklahoma. As of the 2020 census, the population was 796,292,^[1] making it the most populous county in Oklahoma. The county seat is Oklahoma City,^[2] 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 being Arkansas County, Hawaii County, Idaho County, Iowa County, New York County (Manhattan), and Utah County), and the only one of the seven to contain the state capital, and one of two to contain a city of the same name as well.^[3]

The area that would someday be called Oklahoma County was originally inhabited by members of the indigenous nations of the Southern Plains, but by the 1830s the land would become part of the territory assigned to the Seminoles and Creeks after their removal from their ancestral lands in the Southeastern USA.^[4]

As a result of the Reconstruction era treaties signed between the US government and the Seminole and Creek nations in 1866, the land was taken from tribal jurisdiction but not assigned to other tribal governments, which in time led it to be called the Unassigned Lands. In 1889, the US federal government held a land run for the Unassigned lands, which led to the rapid settlement of the area.^[5]

By 1890, Oklahoma County was called "County Two" and was one of seven counties established by the Organic Act of 1890.^[4]

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.^[6]

According to the U.S. Census Bureau, the county has a total area of 718 square miles (1,860 km²), of which 709 square miles (1,840 km²) is land and 9.6 square miles (25 km²) (1.3%) is water.^[7]

At the 2020 U.S. census, its population increased to 796,292, with a 2022-estimate at 802,559. Racially, the 2021 American Community Survey estimated 54.5% were non-Hispanic white, 15.8% Black or African American, 4.7% Asian, 0.1% Pacific Islander, 5.8% multiracial, and 18.5% Hispanic or Latino of any race.

The median value of an owner-occupied housing unit was $164,000 from 2017 to 2021, and the median gross rent was $929.

Approximately 16.3% of the population lived at or below the poverty line.^[16]

Since the second half of the 20th century, Oklahoma County has been quite 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. It was one of the few areas in the South where Jimmy Carter didn't do well.

However, the Republican share of votes for president has decreased in every election since the 2004 election (with the exception of 2024). In the 2022 Oklahoma gubernatorial election, Democratic candidate Joy Hofmeister received her largest vote share of any county, with 55.0% of the vote and a modest improvement over the 2018 Democratic candidate, Drew Edmonson.^[18] Incumbent Republican Governor Mary Fallin was the last member of her party to win the county with 51.3% in 2014.^[19] 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, thereby changing parties.^[20] Horn would carry the county again in her 2022 Senate run, becoming the first Democratic Senatorial candidate to carry the county since David Boren's 1990 landslide.^[21][22] In the 2020 United States Presidential election, Republican Donald Trump narrowly carried the county (1% margin), down from 10 points in 2016. It was also the best showing for a Democrat in the county since LBJ. In 2024, Trump won the county, but again by a narrow plurality. However, his margin of victory was slightly larger than in 2020.
