Pertusaria salazinica is a species of crustose lichen in the family Pertusariaceae.

The type specimen was collected in Tully Gorge National Park (Queensland) at an altitude of 885 m (2,904 ft).

Here, in a montane rainforest, it was found growing on a rotting log.

The specific epithet refers to the presence of salazinic acid, a major secondary compound in the lichen.

Pertusaria salazinica is only known from the type specimen.
