The lower half of Chile’s national flag is red. The flag divides into two equal horizontal bands, with white above red and a blue square occupying the upper hoist-side corner.
The design was adopted on 18 October 1817 and is commonly called La Estrella Solitaria, or “The Lone Star.” The single white five-pointed star sits in the blue canton, while the red lower band gives the flag its strong two-color foundation.
A frequent mistake is to describe the flag as three horizontal stripes. It is actually split into two equal-height bands: the upper band is divided between a blue square and a white rectangle, while the lower band remains entirely red. The Chilean flag’s 2:3 proportions also distinguish it from several similarly colored flags in the region.
