Eolactoria is an extinct genus of boxfish that lived during the Lutetian epoch of the middle Eocene, in Monte Bolca. It had two pairs of long spines, one over each eye, and one pair beneath the anal and caudal fins, arranged very similarly to those possessed by the modern genus Lactoria (e.g., "cowfish"), but were, in comparison, much longer. Eolactoria sorbinii had a 5th spine between the two eye-spines, arranged and looking very much like a nose.

The only known fossil specimen is about 5 centimeters in length.
