The Flag of Central Java, Indonesia, is the official symbol representing the province of Central Java. Adopted on October 27, 1950, the flag features a white field divided into two equal rectangles by a diagonal stripe that slants from the upper hoist-side corner to the lower fly-side corner, forming a right-angled isosceles triangle at the center. This triangle, which represents a mountain peak, is filled with three horizontal stripes of red, white, and black, the colors symbolizing courage, purity, and honesty respectively. The flag's overall design reflects Central Java's rich history, cultural diversity, and significance within Indonesia.
