Parablechnum is a genus of ferns in the family Blechnaceae, subfamily Blechnoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I).[1] The genus is accepted in a 2016 classification of the family Blechnaceae,[2] but other sources sink it into a very broadly defined Blechnum, equivalent to the whole of the PPG I subfamily.[3]
