Greater St. Louis is the metropolitan area that completely surrounds and includes the independent city of St. Louis (the principal city). It includes parts of both the U.S. states of Missouri and Illinois. The city core is on the border with Illinois and collectively the two regions form the combined metropolitan area. St. Louis is the largest metro area in Missouri, and is the second largest in Illinois. St. Louis County is independent of the city of St. Louis and their two populations are generally tabulated separately.

Depending on the counties included in the area, it can refer to the St. Louis, MO-IL metropolitan statistical area (MSA) or the St. Louis-St. Charles-Farmington, MO-IL combined statistical area (CSA). As well as the city St. Louis, the area serves the Southern Illinois counties of Bond, Calhoun, Clinton, Jersey, Macoupin, Madison, Monroe, and St. Clair (known collectively as the Metro East); the Missouri counties of Franklin, Jefferson, Lincoln, St. Charles, St. Louis County (separate from and not inclusive of the city of St. Louis), Warren, Washington, and a portion of Crawford County. The CSA includes all of the MSA listed above and the Farmington, MO micropolitan statistical area, which includes Washington and St. Francois Counties. The CSA was the 19th largest in the United States in 2015, with a population of 2,916,447, while the MSA was the 20th largest in the country that year with a population of 2,811,588.
