Aloe aldabrensis (the "Aldabra Aloe", previously Lomatophyllum aldabrensis) is a species of Aloe endemic to the islands of Aldabra in the Indian Ocean, where it can still be found in coastal scrub on limestone-based soil.

These species are also more distantly related to Aloe purpurea of Mauritius, but differ by their larger leaves, longer flowers, and more widely interspaced leaf-teeth.

The Aldabra aloe usually grows singly, close to the ground, with at most a short stem.

Its leaves are green with red or orange tints.

Its multi-branched inflorescence bears orange-red flowers in racemes, and its seeds develop in fleshy berries.
