Willeya laevigata is a species of saxicolous (rock-dwelling), crustose lichen in the family Verrucariaceae.

Found in northwest Vietnam, it was formally described as a new species in 2014 by Cécile Gueidan.

The type specimen was found growing on shaded calcareous rock outcrops in a rainforest in the Mai Châu district of Hòa Bình province.

The species epithet laevigata refers to the smooth upper surface of the thallus.
