Mexico's national flag is a vertical tricolor of green, white, and red, distinguished by the coat of arms centered on the white stripe. The emblem shows an eagle perched on a prickly pear cactus with a serpent in its beak, a scene tied to the Mexica foundation story of Tenochtitlan. This central design sets the Mexican flag apart from other green, white, and red tricolors. The category brings together flag imagery associated with Mexico, with the national flag as its defining symbol.
