Beaumontoperca is an extinct genus of freshwater or estuarine temperate bass known from Late Oligocene.

It contains a single species, B. beaumonti, from the Niveau du gypse d'Aix Formation of Aix-en-Provence, France.

[1][2][3] Initially described by Louis Agassiz as Perca beaumonti, it was moved into its own genus, Beaumontoperca, in 2000 following further studies.

It is considered to likely be a member of the Moronidae due to the morphology of its saccular otolith.
