The fleur-de-lis, also spelled fleur-de-lys (plural fleurs-de-lis or fleurs-de-lys), is a common heraldic charge in the shape of a lily (in French, fleur and lis mean 'flower' and 'lily' respectively). Most notably, the fleur-de-lis is depicted on the traditional coat of arms of France that was used from the High Middle Ages until the French Revolution in 1792, and then again in brief periods in the 19th century. This design still represents France and the House of Bourbon in the form of marshalling in the arms of Spain, Quebec and Canada, for example.
Other European nations have also employed the symbol. The fleur-de-lis became "at one and the same time, religious, political, dynastic, artistic, emblematic, and symbolic," especially in French heraldry. The Virgin Mary and Saint Joseph are among saints often depicted with a lily.

According to Pierre-Augustin Boissier de Sauvages, an 18th-century French naturalist and lexicographer:
The old fleurs-de-lis, especially the ones found in our first kings' sceptres, have a lot less in common with ordinary lilies than the flowers called flambas [in Occitan], or irises, from which the name of our own fleur-de-lis may derive. What gives some colour of truth to this hypothesis that we already put forth, is the fact that the French or Franks, before entering Gaul itself, lived for a long time around the river named Lys in the Flanders. Nowadays, this river is still bordered with an exceptional number of irises —as many plants grow for centuries in the same places—: these irises have yellow flowers, which is not a typical feature of lilies but fleurs-de-lis. It was thus understandable that our kings, having to choose a symbolic image for what later became a coat of arms, set their minds on the iris, a flower that was common around their homes, and is also as beautiful as it was remarkable. They called it, in short, the fleur-de-lis, instead of the flower of the river of lis.
