The Granitic Seychelles are the islands in the Seychelles which lie in central position on the Seychelles Bank and are composed of granite rock. They make up the majority of the Inner Islands, which in addition include the coral islands along of the rim of the Seychelles Bank, namely Bird Island and Denis Island.

There are mafic xenolith intrusions in the granite in some areas. The Granitic Seychelles are fragments of the ancient supercontinent of Gondwana, and have been separated from other continents for 75 million years. The Granitic Seychelles form the nothernmost part of the Mascarene Plateau.
