The flag of Sint Eustatius was adopted on 16 November 2004 (Statia Day). The island's flag was designed by Zuwena Suares.
The flag is rectangular with the colors blue, red, white, gold and green, and divided in four five-sided blue polygons, each fimbriated red. In its center is a diamond-form white field; in the diamond is the silhouette of the island in green. In the center in the top of the diamond is a five-pointed golden star.
