Leiostyla relevata is a species of small air-breathing land snail in the family Lauriidae.

It is endemic to Ilhéu de Baixo, an islet near Porto Santo Island in the Madeira archipelago.

[1] This snail is only known from a single site on the wet seaside cliffs of the islet.

The population, though small, is likely stable because the island is isolated from most threats.
