The Nordic flags share a distinctive design known as the Nordic Cross, a symbol that traces its origins to medieval Scandinavia and reflects the region’s shared cultural and historical heritage. First appearing on the Danish flag, the Dannebrog, this cross motif later spread across the Nordic world.
Today, variations of the Nordic Cross are used not only by the Nordic states — Denmark, Sweden, Norway, Finland, and Iceland — but also by several regions and territories influenced by Nordic history. While colors differ, the design highlights a common identity shaped by geography, tradition, and centuries of close ties across Northern Europe.
