The coat of arms of the Autonomous Region of Madeira was established by Regional Legislative Decree n.º 11/91/M, on 24 April 1991.
The central shield is blazoned, azure a pale or charged with a Cross of Christ.
The monk seals supporting the shield in the coat of arms are an homage to the only large mammals found by the first inhabitants of the island, and allude to the need to preserve this endangered species.
The gold armillary sphere represents the Age of Discovery, initiated by the Portuguese, and King Manuel I of Portugal who ordered the settling of the archipelago.
The Autonomous Region of Madeira motto, Das Ilhas as Mais Belas e Livres, is Portuguese for "Of all islands, the most beautiful and free".
