The term "List of Mexican flags" covers a broad set of banners and ensigns used in the United Mexican States at national, regional, civic and military levels. The best known is the national tricolor — green, white and red — charged with the national coat of arms. For a detailed account of that single flag and its symbolism, see the Flag of Mexico.
Categories and common characteristics
Flags in Mexico are usually grouped into several categories: national flags (current and historical); flags of the federal entities (states and Mexico City); municipal banners; military, naval and governmental standards; and historical or revolutionary banners. Many state and municipal flags follow a pattern of a plain field, often white, bearing the local coat of arms or seal; national and military flags typically use the tricolor palette.
Historical and notable variants
Mexico's national emblem and flag have changed over time in response to political shifts — from independence and empire, through republican and revolutionary eras, to the modern republic. Historical banners include early independence standards, imperial standards from the First Empire, and revolutionary flags used by regional movements. Changes often involved the depiction of the eagle and serpent in the coat of arms and the arrangement or proportions of the tricolor.
State, municipal and indigenous flags
Each of Mexico's 31 states and Mexico City has its own flag or official banner, commonly featuring the state coat of arms. Municipalities sometimes adopt local flags for civic events. In recent decades there has also been growing recognition of indigenous community symbols and banners used in local contexts, though these are diverse and not standardized at the national level.
Military, naval and governmental standards
Armed forces and government institutions use specific flags and standards: units, branches and commands may have distinctive colors and emblems; naval flags and pennants denote warships, merchant vessels and naval ranks; the presidency and other high offices use personal or institutional standards. These flags are governed by protocol and law regarding display and respect.
Uses, display and distinctions
Flags in Mexico serve ceremonial, institutional and identity purposes: national holidays, governmental buildings, military parades, and local celebrations. Legal norms regulate the use and treatment of the national flag more strictly than local banners. Collectors and scholars distinguish between official flags, historical reproductions and unofficial or popular variants, making catalogs and lists useful for education, protocol and heritage preservation.
