List of endemic plants of Seychelles

The Granitic Seychelles are a group of islands which form the main part of the island country Seychelles. These islands sit on the Seychelles Bank and composed mostly of granite derived from ancient continental crust. The Granitic Seychelles are home to several dozen endemic species and subspecies of plants, including the endemic genera Deckenia, Glionnetia, Lodoicea, Medusagyne, Nephrosperma, Northia, Paragenipa, Phoenicophorium, and Protarum, Roscheria, Vateriopsis, Verschaffeltia, and Xyroschoenus.

Aldabra and Seychelles' other coralline islands – the Amirante Islands, Farquhar Group, and Southern Coral Group (Coëtivy and Île Platte) – which are known as the Outer Islands or Coralline Seychelles, are politically part of Seychelles, but the World Geographical Scheme for Recording Plant Distributions treats them a separate botanical country.

Plants are listed alphabetically by plant family. Plants endemic to specific islands are indicated.
