The 🇷🇪 emoji represents the flag of Réunion, an overseas department and region of France located in the Indian Ocean. The flag features a blue background with a white cross that extends to the edges of the flag, dividing it into four quadrants. Each quadrant contains a symbol: a red square with a white Maltese cross in the top left, a white circle with a red flame in the top right, a yellow diamond shape in the bottom left, and a red triangle in the bottom right.
