Neopeckia is a genus of fungi in the class Dothideomycetes. The relationship of this taxon to other taxa within the class is unknown (incertae sedis). The genus name of Neopeckia is in honour of Charles Horton Peck (1833–1917), who was an American mycologist. He has described over 2,700 species of North American fungi. The genus was circumscribed by Pier Andrea Saccardo in Bull. Torrey Bot. Club vol.10 on page 127 in 1883.
