The flag of St. Louis, Missouri, consists of a solid red background and three thick, wavy lines colored blue and white extending from the top left corner, bottom left corner, and center right edge. At the intersection of these lines there is a yellow disk containing a blue fleur-de-lis. (In heraldic terms this is a white-fimbriated dark blue pall on a red field with a bezant.)

The flag was designed by Yale University professor Theodore Sizer and officially adopted in 1964.^[1]

In a 2004 poll on the North American Vexillological Association website, St. Louis’ flag was voted the fifth-best design among United States city flags.^[2]
