Paraporpidia is a genus of lichen-forming fungi in the family Lecideaceae. It has three species of saxicolous (rock-dwelling) crustose lichens. The genus was circumscribed by Gerhard Rambold and M. Pietschmann in 1989, with Paraporpidia aboriginum assigned as the type species.
A fourth species, Paraporpidia neotropica, was proposed by André Aptroot and Felix Schumm in 2023. It occurs in Brazil.
