Louisiana is a state in the Deep South and South Central regions of the United States. It borders Texas to the west, Arkansas to the north, and Mississippi to the east. Of the 50 U.S. states, it ranks 31st in area and 25th in population, with roughly 4.6 million residents. Reflecting its French heritage, Louisiana is the only U.S. state with political subdivisions termed parishes, which are equivalent to counties, making it one of only two U.S. states not subdivided into counties. Baton Rouge is the state's capital, and New Orleans, a French Louisiana region, is its most populous city with a population of about 363,000 people. Louisiana has a coastline with the Gulf of Mexico to the south; a large part of its eastern boundary is demarcated by the Mississippi River.

New Orleans is a consolidated city-parish located along the Mississippi River in the U.S. state of Louisiana. With a population of 383,997 at the 2020 census, New Orleans is the most populous city in Louisiana, the second-most populous in the Deep South after Atlanta, and the twelfth-most populous in the Southeastern United States; the New Orleans metropolitan area with about 1 million residents is the 59th-most populous metropolitan area in the nation. New Orleans serves as a major port and commercial hub for the broader Gulf Coast region. The city is coextensive with Orleans Parish.
