Anogramma ascensionis (Ascension Island parsley fern) is a species of fern in the Pteridaceae family that is endemic to Ascension Island, a volcanic island in the South Atlantic Ocean. It is one of eight putative species in the Anogramma genus. It was thought to have become extinct due to habitat loss, until four plants were found on the island in 2010. Over 60 specimens were then successfully cultivated at Royal Botanic Gardens, Kew and on Ascension Island. It is now classified as Critically Endangered.
