Thérèse Island is a small island in the inner Seychelles archipelago, situated in the western Indian Ocean. It is one of the numerous granitic and coralline islands that form the central Seychelles group.

The island is compact and typically features coastal vegetation and rocky or sandy shoreline areas common to small Seychelles islands. It does not have widely reported large-scale infrastructure or urban development.

Detailed historical or ownership records for the island are found in local Seychelles sources; many islands in the inner archipelago have histories of traditional use, plantation agriculture or private ownership at various times.

Geographically it sits among the inner islands of the Seychelles, in proximity to the main island of Mahé and the central cluster of islands within the Republic of Seychelles.
