Regnellidium is a monotypic genus of ferns of family Marsileaceae.

The single species, Regnellidium diphyllum, Two-leaf Water Fern, is native to South Eastern Brazil and adjacent Argentina. It resembles its relatives from the genus Marsilea, but has 2-lobed leaves (rather than 4) and also contains latex.

This fern is sometimes grown in aquaria.
