With nearly 200 country flags in the world, some overlap in design was inevitable. Here are the most notable countries with similar flags.
Countries with Nearly Identical Flags
- Indonesia and Monaco — both use a simple red-over-white horizontal bicolor, differing only in exact proportions
- Chad and Romania — both use a vertical blue-yellow-red tricolor, nearly identical except for a very slightly different shade of blue
- Ireland and Ivory Coast (Côte d’Ivoire) — both use a green-white-orange vertical tricolor, but with the colors in reverse order
- Colombia, Ecuador, and Venezuela — all use a yellow-blue-red horizontal tricolor, a shared legacy of Gran Colombia, the early-1800s union that once included all three
- Australia and New Zealand — both feature the Union Jack in the canton alongside the Southern Cross constellation, differing mainly in star count and color

Why Flags End Up Looking Alike
Shared flag designs usually trace back to a common historical or political origin: Colombia, Ecuador, and Venezuela’s flags all descend from Gran Colombia, the short-lived state that once united them. Chad and Romania’s resemblance, on the other hand, is coincidental — the designs were adopted independently and unrelated historically, which has occasionally caused real diplomatic friction between the two countries over the similarity.
