Lecanactis leprarica is a species of lichen in the family Roccellaceae.

Found in Cameroon, it was described as a new species in 2021 by lichenologists Klaus Kalb and André Aptroot.

The type was collected near the Bewala Campala village (Eastern Province), at an altitude of about 700 m (2,300 ft).

The specific epithet leprarica refers to its main secondary chemical, lepraric acid.

Both the thallus and apothecia of the lichen turn red with the K chemical spot test.
