The Flag of Grand Lyon France is a heraldic emblem representing the metropolitan area of Lyon, France. Consisting of three horizontal bands, it reflects the administrative divisions within the region. The top band is blue (Azure), symbolizing Rhne department; the middle band, white (Argent), represents the Metropolis of Lyon; and the bottom band, red (Gules), signifies the department of Mtropole de Lyon. The flag was adopted in 2015 when the regional structure was reorganized, combining the urban areas surrounding Lyon into a single administrative entity. This design embodies the unity and diversity of Grand Lyon as a vibrant and dynamic region in eastern France.
