Menegazzia abscondita is a species of foliose lichen in the family Parmeliaceae. Found in Australasia, the species was described as new to science by Australian lichenologist Gintaras Kantvilas in 2012. The type specimen was collected along Gordon River Road in Tasmania at an altitude of 340 m (1,120 ft). Here it was found growing on satinwood (Nematolepis squamea) at the edge of a wet eucalypt forest. The specific epithet abscondita means "hidden", and refers to "the effort required to collect sufficient material upon which to base its description".
