The flag of Eritrea comprises three triangles — a large red isosceles triangle with its base spanning the hoist end and its apex at the midpoint on the fly end, and a green and blue right-angled triangle above and beneath the red triangle. On the hoist side of the red triangle is a golden vertical olive branch encircled by a golden olive wreath.
