Caddo Parish (French: Paroisse de Caddo) is a parish located in the northwestern corner of the U.S. state of Louisiana. According to the 2020 U.S. census, the parish had a population of 237,848. The parish seat is Shreveport, which developed along the Red River.
 The city of Shreveport is the economic and cultural center for the tri-state region of the Ark-La-Tex containing Caddo Parish. Caddo Parish is included in the Shreveport–Bossier City metropolitan statistical area.
 In 1838, Caddo Parish was created by territory taken from Natchitoches Parish; the legislature named it for the indigenous Caddo Indians who had lived in the area. Most were forced out during Indian Removal in the 1830s.
 With European-American development, the parish became a center of cotton plantations. Planters developed these along the waterways, with clearing and later cultivation and processing by thousands of enslaved African-American laborers. Shreveport, the parish seat, became a center of government, trade and law.
 An armory was constructed in Shreveport before the American Civil War. This city served as the state capital after Union forces had seized Baton Rouge. Locals have referred to the armory as "Fort Humbug".
 After the Civil War, and particularly after Reconstruction, whites in the parish used violence and intimidation against blacks to suppress Republican voting and re-establish white supremacy. The parishes in northwestern Louisiana had a high rate of violence and lynchings. From 1877 through the early 20th century, there were 48 lynchings of African Americans in Caddo Parish; this was the second-highest total in the state after Lafourche Parish, and nearly twice as high as the lowest parishes among the top six. The victims included Jennie Steers, a domestic servant hanged by a white lynch mob in July 1903, for allegedly poisoning her employer's daughter.
 In 1920 the Daughters of the Confederacy, who were memorializing the Civil War, designated the armory as "Fort Turnball". During World War II, the government used it as a mobilization site for men who had been drafted and recruited.
 In the early twentieth century, the oil industry developed here, with a concentration of related businesses in Shreveport. Numerous oil wells were constructed across southern Arkansas and northern Louisiana.
 According to the U.S. Census Bureau, the parish has a total area of 937 square miles (2,430 km2), of which 978 square miles (2,530 km2) is land and 58 square miles (150 km2) (6.2%) is water.

 Since the late 20th century, most conservative whites in Louisiana have shifted into the Republican Party. Politics largely follows ethnic patterns, as most African Americans have supported national Democratic candidates since regaining the power to vote and other civil rights under Democratic national administrations. Some urban liberal whites also vote Democratic. Since 1980, Caddo Parish has voted for the overall national popular vote winner in presidential campaigns. Notably the city of Shreveport is the base for Democratic strength, while surrounding white-majority suburban areas are aligned with the Republican Party.

 The Louisiana Department of Public Safety & Corrections operated the Forcht-Wade Correctional Center in Keithville, an unincorporated section of Caddo Parish. As the state succeeded in reducing the number of prisoners, it closed this facility in July 2012.
 The Caddo Correctional Center is a full-service parish jail rated at a capacity of 1,500 beds. Constructed in 1994, this facility was designed to successfully manage a large number of inmates with a minimum of personnel. The Caddo Correctional Center is the largest jail in the Ark-La-Tex and the only "direct supervision" facility in the state.[citation needed]
