If you've ever looked for the Saint Louis flag and found yourself viewing the St. Louis flag instead, you may be wondering if they are actually identical. Though the names sound nearly the same, they can be used in different senses. The Saint Louis flag tends to refer to the historical or cultural citation of the city's French heritage, while the St. Louis flag tends to denote the contemporary, official emblem of the city itself.


Both flags belong to the same proud community, but each possesses its own tale, design, and symbolism.


The St. Louis Flag: The Official City Symbol

The St. Louis flag, created in 1964 by Theodore Sizer, is the City of St. Louis official municipal flag. It's widely respected among flag enthusiasts as having a clean aesthetic and rich symbolism.


Three wavy lines symbolize the Mississippi, Missouri, and Meramec Rivers.

  • Gold fleur-de-lis commemorates King Louis IX of France, the city's namesake.
  • White converging lines represent the convergence of the rivers and unification of the people.
  • Red, white, and blue colors signify patriotism and the French heritage of the city.


The Saint Louis Flag: A Wider Historical and Cultural Reference


When individuals refer to a "Saint Louis flag," they might be talking about banners commemorating the wider history of the region, frequently associated with French colonialism or Catholic heritage, because King Louis IX was made a saint.


Such flags might feature historical French symbols, coats of arms based on European heraldry, or religious motifs celebrating Saint Louis. They are frequently displayed in museums, heritage events, or community festivals.


Why the Distinction Matters


Knowing the difference helps avoid confusion in conversations about civic pride, history, or flag purchases. The St. Louis flag is seen on official buildings and documents, while the Saint Louis flag is often tied to historical reenactments or cultural events.


Collectors should be clear about which version they want, especially if they’re looking for an American-made flag for home or work.


Where You’ll See Each One
