'''Parkerioideae''', synonym '''Ceratopteridoideae''', is one of the five subfamilies in the fern family Pteridaceae. It includes only the two genera ''Acrostichum'' and ''Ceratopteris''.<ref name=PPGI/><ref name=Christenhusz-2011/> The following diagram shows a likely phylogenic relationship between the two Parkerioideae genera and the other Pteridaceae subfamilies.<ref name=Schuettpelz-2008/>
