The Terre-de-Haut racer (Alsophis sanctonum) is a species of snake found in the Caribbean, on the Lesser Antilles. This species is endemic to Terre-de-Bas Island and Terre-de-Haut Island which make up the Îles des Saintes. Terre-de-Bas and Terre-de-Haut are very small islands with a total area of approximately 13 km2. Because of its presence only on this small area, it is a highly protected species.
