Sardolutra ichnusae is an extinct species of otter from the Late Pleistocene of Sardinia. It was originally described as Nesolutra ichnusae.{{cite journal |author=A. Malatesta |year=1977 |title=The skeleton of Nesolutra ichnusae sp n a Quaternary otter discovered in Sardinia. |journal=Geologica Romana |volume=16 |pages=173–209}} It was a rather small species of otter, probably living in the sea. Among its characteristics is a relatively very large baculum, larger than in any living otter.

The species probably evolved from a species of Lutra, maybe L. castiglionis.{{cite journal |author=G.F. Willemsen |year=1992 |title=A revision of the Pliocene and Quaternary Lutrinae from Europe. |journal=Scripta Geologica|volume=101 |pages=1–115}}
