The most complete flag encyclopedia on the internet

We don't just show flags. We explain them.

Any website can show you a colored rectangle. We tell you why Jamaica's flag is the only one in the world with no red, white or blue; which real constellation is mapped on Brazil's; or why the Philippines flies its flag upside down in wartime. Every flag page includes:

• The meaning of every color and every symbol, one by one
• The full history: who designed it, when it was adopted and what came before it
• Verified trivia and a construction sheet with official proportions
• Similar flags it gets confused with, so you never mix them up again

What Makes Us Different

• Real coverage, not just countries. All 193 UN member states are here without exception, plus observers and de facto states. And beyond them: states and regions across 12 countries (from US states to Swiss cantons), 213 cities and 235 historical flags. Most flag sites stop at the 200 countries.
• Editorial content on every page. No empty templates: every flag has its researched history and verified trivia.
• Cleanly licensed images. Everything comes from public domain and freely licensed sources, mainly Wikimedia Commons. When a flag is under copyright (yes, that exists), we do not publish it.
• Alive and growing. Flags change: countries redesign, cities adopt new ones. We add and correct continuously, even based on what our visitors search for.
