Fiandraia is an extinct monotypic genus of notoungulate that lived in Uruguay during the Oligocene and the Early Miocene.[1] It was found in the Fray Bentos Formation, in rocks dated back from the Deseadan period.[2]

The taxonomic status of Fiandraia has been historically disputed; in 1976, its discoverer, Roselli, assigned it in the family Mesotheriidae;[1] in 1978, in Mones & Ubilla, it was considered part of Interatheriidae;[2] McKenna & Bell, in 1997, placed it inside its own family, Fiandraiinae, itself part of Mesotheriidae;[3] Flynn et al considered it, in 2005, as a member of the Toxodontidae instead of the Mesotheriinae.[1]
