Odessa (/ˌoʊˈdɛsə/) is a city in the U.S. state of Texas and the seat of Ector County with portions extending into Midland County.

Odessa's population was 114,428 at the 2020 census, making it the 28th-most populous city in Texas; it is the principal city of the Odessa metropolitan statistical area, which includes all of Ector County. The metropolitan area is also a component of the larger Midland–Odessa combined statistical area, which had a 2020 census population of 359,001.

The city is famous for being featured in the book Friday Night Lights: A Town, a Team, and a Dream, and the movie adaption, Friday Night Lights.

In 1948, Odessa was also the home of First Lady Barbara Bush, and the onetime home of former Presidents George H. W. Bush and George W. Bush. Former President George H. W. Bush has been quoted as saying "At Odessa we became Texans and proud of it."

Odessa was founded in 1881 as a water stop and cattle-shipping point on the Texas and Pacific Railway. The first post office opened in 1885. Odessa became the county seat of Ector County in 1891 when the county was first organized. It was incorporated as a city in 1927, after oil was discovered in Ector County on the Connell Ranch southwest of Odessa.

Odessa is said to have been named after Odesa, a coastal city in Southern Ukraine, (historically spelled Odessa) because of the local shortgrass prairie's resemblance to Ukraine's steppe landscape.

With the opening of the Penn Field in 1929, and the Cowden Field in 1930, oil became a major draw for new residents. In 1925, the population was just 750; by 1929, it had risen to 5,000. For the rest of the 20th century, the city's population and economy grew rapidly during each of a succession of oil booms (roughly in the 1930s–1950s, 1970s, and 2010s), often with accompanying contractions during the succeeding busts (particularly in the 1960s and 1980s).

Odessa is located along the southwestern edge of the Llano Estacado in West Texas. It is situated above the Permian Basin, a large sedimentary deposit that contains significant reserves of oil and natural gas.

According to the United States Census Bureau, the city has a total area of 44.0 square miles (114 km2); 43.9 square miles (114 km2) are land and 0.1 square miles (0.26 km2) (0.05%) is covered by water.

Odessa has a desert climate typical of West Texas. Summers are hot and sunny, while winters are mild and dry. Most rainfall occurs in late spring and summer; snowfall is rare. The area exhibits a large diurnal temperature range and frequent high winds.

Historically, the Odessa economy has been primarily driven by the area's oil industry, booming and busting in response to rises and falls in the crude oil price. Many of the city's largest employers are oilfield supply companies and petrochemical processing companies. In recent decades, city leaders have begun trying to decrease the city's reliance on the energy industry to moderate the boom-bust cycle and develop greater economic sustainability.

Odessa has also taken steps to diversify the energy it produces. In 2009, a wind farm has been constructed in northern Ector County. Around the same time, a coal pollution mitigation plant had been announced for a site previously entered in the Futuregen bidding. The plant will be run by Summit Power and will be located near Penwell. This plant was supposed to lead to the creation of 8,000 jobs in the area. Plans were also in place for a small nuclear reactor called the High-Temperature Teaching and Test Reactor to be run as a test and teaching facility in conjunction with the nuclear engineering department at University of Texas of the Permian Basin.

Odessa's main enclosed shopping mall, Music City Mall, used to include an indoor skating rink.

As in many municipalities, some of the largest employers are in the education, government, and healthcare industries. Outside of those areas, the city's major employers are concentrated in the oil industry. According to the city's 2021 Comprehensive Annual Financial Report, the top employers in the city were:

The University of Texas Permian Basin (UTPB) began in 1973. UTPB was an upper level and graduate university until the Texas Legislature passed a bill in spring 1991 to allow the university to accept freshmen and sophomores. As of 2006, the university was holding discussions with the Nuclear Regulatory Commission about the construction of a new High-Temperature Teaching and Test Reactor, which if successful, would finish licensing and construction around 2012. It would be the first university-based research reactor to be built in the US in roughly a decade, and be one of the few HTGR-type reactors in the world. In January 2006, UTPB's School of Business was awarded accreditation by the Association to Advance Collegiate Schools of Business International, which is generally regarded as the premier accreditation agency for the world's business schools. According to the university, only 30% of business schools in the United States, and 15% of world business schools, have received AACSB accreditation.
