Shreveport ( SHREEV-port) is a city in the U.S. state of Louisiana. It is the third most populous city in Louisiana after New Orleans and Baton Rouge. The Shreveport–Bossier City metropolitan area, with a population of 393,406 in 2020, is the fourth largest in Louisiana, though 2020 census estimates placed its population at 397,590. The bulk of Shreveport is in Caddo Parish, of which it is the parish seat. It extends along the west bank of the Red River (most notably at Wright Island, the Charles and Marie Hamel Memorial Park, and Bagley Island) into neighboring Bossier Parish. The United States Census Bureau's 2020 census tabulation for the city's population was 187,593, though the American Community Survey's census estimates determined 189,890 residents.

Shreveport was founded in 1836 by the Shreve Town Company, a corporation established to develop a town at the juncture of the newly navigable Red River and the Texas Trail, an overland route into the newly independent Republic of Texas. Prior to Texas becoming independent, this trail entered Mexico. It grew throughout the 20th century and, after the discovery of oil in Louisiana, became a national center for the oil industry. Standard Oil of Louisiana (absorbed by Standard Oil of New Jersey and now part of ExxonMobil) and United Gas Corporation (now part of Pennzoil) were headquartered in the city until the 1960s and 1980s. After the loss of jobs in the oil industry, the close of Shreveport Operations (a General Motors vehicle factory), and other economic problems it struggled with a declining population, poverty, drugs and violent crime. However, the city continues in its efforts to revitalize its infrastructure, revive the economy through diversification, and lower crime. Despite these efforts, the city witnessed the largest number of homicides in its recorded history in 2021, eclipsing the previous record set in 1993.
