The Flag of Landes is the official heraldic banner representing the French department of Landes, located in southwestern France. Adopted on March 20, 1946, the flag consists of a blue field with three golden (yellow) acorns arranged in a vertical row at the hoist side and five gold fleurs-de-lis arranged in a saltire on the remaining area. The acorns symbolize the oak forests that cover much of the department, while the fleurs-de-lis represent Aquitaine, the region from which Landes originated. The flag is used for ceremonial purposes and regional promotion, fostering a strong sense of identity among the people of Landes France.
