Midwest City is a city in Oklahoma County, Oklahoma, United States, and a part of the Oklahoma City metropolitan area. As of the 2020 census, the population was 58,409, making it the eighth largest city in the state.

The city was developed in response to talk of an air field being located nearby and named for the Tinker Air Force Base's original designation as the Midwest Air Depot. The city suffered damage during two tornadoes, the first in May 1999 and the second on May 8, 2003.

W.P. "Bill" Atkinson bought land in the area that would become Midwest City after hearing speculation that an air field was going to be built nearby. The city, which was incorporated on March 11, 1943, was named for the air field's original designation as the Midwest Air Depot. When Major General Clarence L. Tinker of Pawhuska, Oklahoma became the first American general killed in World War II (June 7, 1942) near Wake Island, the airfield was renamed in his honor.

Seward Mott, the director of the Federal Housing Administration's Land Planning Division, helped design the city, gaining national print and broadcast attention, and it became a model for postwar community development. The city incorporated the Mishak community of Czech and German immigrants that had formed in what now is the southeast part of the city.

In 1947, returning veteran Nicholas Harroz opened Nick's Brett Drive Grocery, which later became Crest Discount Foods, which is now one of the largest discount chains in the Oklahoma City metro area. Soon after its opening, Midwest City citizens opted for a charter-council-city manager form of government to better manage their rapid growth.

Midwest City's regional hospital was dedicated October 6, 1962, built with the use of bond money. Voters also approved the creation of a junior college district in 1968. Oscar Rose Junior College opened its doors to students in 1970 and is now known as Rose State College. The Heritage Park Mall opened in 1978 on North Air Depot and was a prime shopping area in the city for several decades. The first Sam's Club was opened in Midwest City on April 7, 1983.

In the early 1970s, the Glenwood Addition subdivision, just north of the TAFB runway, was purchased from individual owners with funds raised in a county-wide bond election after plane crashes in the area killed several civilians and military crewmen. 835 homes were moved and an elementary school was closed down. The former subdivision is fenced off and used as storage and training exercises for TAFB personnel.

Portions of Midwest City particularly northwest of Tinker Air Force Base sustained extreme damage from a violent tornado that swept through the southern and eastern areas of the Oklahoma City Metro on May 3, 1999. While it produced F5 damage in South Oklahoma City, damage in Midwest City was rated high-end F4 (although F5 was considered), with numerous destroyed homes and three fatalities. Another strong tornado struck almost exactly the same area four years later on May 8, 2003.

City officials worked to revitalize S.E. 29th Street in the early 21st century, leading to the development of a new Town Center Plaza shopping area that faces Interstate 40 and Tinker Air Force Base. The Town Center Plaza development replaced an aging, largely deserted Atkinson Plaza shopping center. In 2003, the Reed Center, a 60,000-square-foot (5,600 m2) convention center, was built. Meanwhile, the Heritage Park Mall has slowly dwindled, becoming an issue of contention in the 2010 mayoral race.

According to the United States Census Bureau, the city has a total area of 24.6 square miles (64 km2), all land. The city's elevation is 1,157 feet above sea level.

The city is located in Oklahoma County and the area is known for low hills and two species of blackjack oak and post oak. Midwest City also falls into an ecological region known as the Cross Timbers, and the Frontier Country tourism region

Midwest City has a humid subtropical climate (Köppen climate classification Cfa).

Midwest City's economic base is heavily dependent upon Federal tax dollars via Tinker Air Force Base, the largest single-site employer in Oklahoma. Other large employers include the Midwest Regional Medical Center and aerospace industry businesses affiliated with the base. The General Motors Oklahoma City Assembly plant was another major employer from its opening in 1979 until its closure in February 2006. GM closed the plant as part of a cost-savings measure. The property was later acquired by Oklahoma County and leased to Tinker Air Force Base for $1/year. Tinker renamed the facility the Tinker Aerospace Complex.

During World War II, the Midwest City Douglas Aircraft Company Plant constructed more than half of the 10,000 C-47 Skytrain U.S. Army cargo planes. The plant cost $24 million and rolled out its first C-47s in March 1943. Some 38,000 Oklahomans labored at the plant, the majority of them women. The plant closed on August 17, 1945, and was redesignated Building 3001 and transferred to the Oklahoma City Air Technical Service Command on November 1, 1945 and is now the Oklahoma City Air Logistics Center.

Midwest City is home to a four-star 18-hole municipal golf course, a 9-hole municipal golf course, a swimming pool, splash park, and several urban parks. The nearby base hosts an annual Star-Spangled Salute each summer. The Juneteenth Midwest City Family Festival began in 2023 commemorating the national Juneteenth holiday. Rose State College hosts Global Oklahoma each year on the first Saturday in October.

When Midwest City's founder and developer, W. P. "Bill" Atkinson, passed away in 1999, he left his 1955 mansion in trust for the community's enjoyment and historical appreciation. Today, the Atkinson Heritage Center at N.E. 10th and Midwest Blvd. is owned by the Rose State College Foundation and maintained by the college. The 8,000 sq. ft. historic home, preserved in its original design when Atkinson was anticipating a run for governor, is available for free tours by appointment. To serve the community and help financially support the historic property, the house conference room and the 1951 pony barn are available for event rentals.

Midwest City is within the boundaries of multiple school districts. The largest portion is within Mid-Del School District, and includes Midwest City High School, Carl Albert High School, Midwest City Middle School, Carl Albert Middle School and numerous elementary schools. The district also includes a post-secondary school, the Mid-Del Technology Center. Rose State College, a two-year community college, is also located in the city.

The school district was initially housed in prefabricated hutments and began with a high school and two grade schools that were precursors to the Sooner and Soldier Creek elementary schools.

Other parts of Midwest City are in Choctaw/Nicoma Park Schools, Oklahoma City Public Schools (OKCPS), and Crutcho Public School. Zoned schools of the OKCPS part include Willow Brook Elementary School (PreKindergarten-Grade 1), Spencer Elementary School (grades 2-4), Rogers Intermediate School (grades 5-6), and Star Spencer Mid-High School.
