In this work we present a floristic survey of the pteridophytes from the Vila Velha State Park, Ponta Grossa, Paraná. Vila Velha presents an area of 3,803.28 ha, altitudes varying from 800 to 1,100 m and it is mainly represented by natural grasslands surrounding Araucaria forest' spots and the peculiar sandstone formations arised. We have found 152 species, distributed in 54 genera, being Asplenium (11 spp.), Blechnum and Thelypteris (10 spp. each), Pecluma, Polypodium and Trichomanes (7 spp. each) the richest genera. One hundred species were found in the forests, 47 in the grasslands and 60 in the sandstone formations. Twenty-seven species are restricted to Brazil, of which 14 are endemic to the southeast and south Brazil. Special mention is made to Ctenitis bigarellae Schwartsburd et al., Elaphoglossum langsdorffii (Hook. & Grev.) T. Moore, Alsophila capensis subsp. polypodioides (Sw.) Conant and Blechnum australe subsp. auriculatum (Cav.) de la Sota. Identification keys, comments and list of specimens are also presented.
