Description: two equal horizontal bands of white (top) and red; there is a blue square the same height as the white band at the hoist-side end of the white band; the square bears a white five-pointed star in the center.

Protocol dictates that it can hang horizontally or vertically, but the star must always be located in the top-left corner.

The colors have meanings:

• Red: represents blood of patriots who fought for independence.
• White: represents snow of the Andes
• Blue: represents the blue of the skies.
• Single star: stresses the fact that Chile is an unitarian republic, not a federal republic.
