is a second-ring suburb of St. Louis, located in northern St. Louis County, Missouri, United States. The city has a total population of 51,387.
The exact date the first settlers came to the rich, fertile 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 by Francois Dunegant dit Borosier who served as the civil and military commandant. Spanish archives in Havana reveal there were 40 people and 7 plantations in Florissant at the time of the 1787 census. The village called "Fleurissant" 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). .
