Girardia is a genus of freshwater triclad belonging to the Dugesiidae family.
Until 1991 Girardia was considered a subgenus of Dugesia, then it was upgraded to the genus rank. Many works are still using incorrectly the old genus for some Girardia species, mainly for Girardia dorotocephala and Girardia tigrina.
