The flag of the department of Vendée was created on 18 September 1989 by French designer Michel Disle.

Before the French Revolution, Vendée was part of the Poitou region and did not have its own coat of arms and flag.

After passing the Infernal columns, the heart symbol was banned or promoted depending on the political climate.

The coat of arms was created in the first half of the 20th century, it contains a double Sacred Heart on sliver shild and a frame composed of an alternating blue rectangle with gold fleur-de-lis, symbol of France and red rectangle with gold castle, symbol of Poitou.

In March 1999, the association Une Vendée pour tous les Vendéens sued the General Council, arguing that the cross surmounting the double heart made of the logo as a religious symbol, in contradiction with State secularity, which has been established in France in 1905.
