You’re staring at a screen or a flagpole, trying to place that one specific banner. It’s crisp. It’s clean. Just two colors: blue and white. It feels like it should be easy to name, right? But then you realize how many nations actually use this combo. Honestly, it’s a lot.
Whether it’s the deep navy of a Nordic cross or the sky-blue stripes of a South American republic, the question of what countries have a blue and white flag is actually a bit of a rabbit hole. Most people immediately think of Greece or Israel, but there are over a dozen nations—and a few famous territories—that stick strictly to this palette.
The Heavy Hitters: Flags You See Everywhere
When we talk about the most recognizable blue and white designs, Greece usually leads the pack. You’ve seen it on olive oil bottles and travel posters. It’s got those nine horizontal stripes and that white cross in the corner. Locals call it the Galanolefki.
The stripes aren't just for show. Each one represents a syllable in the Greek phrase for "Freedom or Death." That’s pretty intense for a flag that looks so breezy.
Then there’s Israel. This design is deeply personal for the people who fly it. It features two horizontal blue stripes on a white background with the Star of David (the Magen David) smack in the center. The blue isn't just any blue; it’s meant to evoke the tallit, the traditional Jewish prayer shawl. It’s a flag that was essentially born from a religious and cultural garment.
Finland keeps things way more minimal. A simple blue Nordic cross on a white field. That’s it. They call it the Siniristilippu. The white is for the snow that covers the country for half the year, and the blue represents their thousands of lakes. It’s basically a landscape painting condensed into a piece of fabric.

The Central American Connection
If you look at a map of Central America, you’ll notice a weird trend. A bunch of these countries have flags that look almost identical. Blue-white-blue horizontal stripes.
- Honduras: Features five blue stars in the middle.
- El Salvador: Often includes a complex coat of arms in the center.
- Nicaragua: Also uses a coat of arms, usually featuring a triangle and volcanoes.
- Guatemala: Flips the stripes vertically.
Why the copy-paste? Well, they were all once part of the Federal Republic of Central America. When that federation fell apart in the 1830s, the countries kept the colors but tweaked the details. Honduras’s five stars actually represent the five original members of that union. It’s a bit like keeping your ex’s hoodie because it’s comfy, but adding a few patches to make it yours.
The Light Blue Legends: Argentina and Somalia
Argentina is a classic. You can’t watch a World Cup without seeing the Albiceleste. It’s technically light blue and white, with that smiling "Sun of May" in the middle. Manuel Belgrano, the guy who designed it, supposedly looked at the sky during a battle and saw the sun breaking through white clouds and blue sky. Or maybe he just liked the colors of the House of Bourbon. Historians argue about it, but the "sky and clouds" story is the one that stuck.
Somalia’s flag is probably the most "clean" looking one on this list. A single white star on a bright, sky-blue background. It looks remarkably like the United Nations flag, and that’s no accident. The UN helped Somalia through its transition to independence, so they paid homage to that help. Each of the five points on the star represents a region where Somali people traditionally live.
Some You Might Have Missed
Micro-states and island nations often get lost in the shuffle. Take San Marino, for example. It’s a tiny enclave inside Italy, and its flag is a simple horizontal split: white on top, light blue on the bottom. It usually has a coat of arms, but the colors alone are their signature.

Then there’s the Federated States of Micronesia. Their flag is a pale blue—representing the Pacific Ocean—with four white stars arranged in a diamond. Those stars represent the four island groups: Chuuk, Pohnpei, Kosrae, and Yap. It’s quiet, simple, and perfectly captures the vibe of a remote archipelago.
Uruguay is another one that people confuse with Greece or Argentina. It has nine stripes (alternating white and blue) and the Sun of May in the corner. It’s basically the love child of the US flag and the Argentine flag.
Why Blue and White?
So, why are these two colors so popular?
Honestly, it’s mostly about the environment. If your country is surrounded by water, you pick blue. If you have a lot of snow, you pick white. If you want to signal "peace" (which is what white usually stands for in vexillology), you put it in the center.
Blue is also associated with "liberty" and "the heavens" in a lot of Western traditions. When you combine that with white—which symbolizes purity or clarity—you get a color scheme that feels aspirational. It’s less "bloody revolution" (which is what red flags are for) and more "new beginnings and clear horizons."

Quick Checklist for Identifying Them
If you're looking at a flag and trying to figure out which one it is, check these specific markers:
- Look at the stripes: If they are horizontal and blue-white-blue, check the center. Stars? Honduras. Coat of arms? Nicaragua or El Salvador. Sun? Argentina.
- Check for a cross: If it’s a standard cross, it’s Finland. If it’s in the corner with stripes, it’s Greece.
- Spot the star: A big star in the middle of a blue field is Somalia. Small stars in a diamond is Micronesia.
- The Sun: If there’s a sun with a face, you’re looking at Argentina or Uruguay. Argentina has three thick stripes; Uruguay has nine thin ones.
Practical Next Steps
Now that you've got the rundown on what countries have a blue and white flag, you can actually use this info next time you're watching the Olympics or playing a round of GeoGuessr.
If you want to dive deeper, you might want to look into the "Sun of May" history—it's wild how a single weather event in 1810 influenced the flags of two different countries. You could also check out the Scottish Saltire (the white X on blue), which isn't a sovereign country flag but is arguably the most famous blue-and-white banner in history.
Whatever you do, just remember that the shade of blue matters. A "celeste" (sky blue) tells a completely different story than a "navy" or "royal blue."
