Florissant () is a city in St. Louis County, Missouri, within Greater St. Louis. It is a middle class, second-ring northern suburb of St. Louis. Based on 2019 U.S. Census Bureau estimates, the city had a total population of 50,952, making it the 13th-largest city in Missouri and the largest municipality in St. Louis County. The exact date the first settlers went to the Valley of Florissant is unknown, but it is one of the oldest settlements in the state of Missouri. Some historians believe it was settled about the same time as St. Louis. The first civil government was formed in 1786. Spanish archives in Havana reveal 40 people and seven plantations were in Florissant at the time of the 1787 census.
The village, called “Fleurissant”, meaning “Blooming” in English, by its French settlers and “St. Ferdinand” by its Spanish rulers, was a typical French village with its commons and common fields.Originally a separate town, and now an inner suburb of St. Louis, the community was centered on (and frequently called after) the parish of St. Ferdinand. As late as 1889, the town was predominantly French-speaking (while the southern portion of the metropolis was populated by German-speakers). The first train line to the area was constructed in 1878—an extension of the line which went from St. Louis City to Normandy. The last train to Florissant ran on November 14, 1931.
