Electrophorus voltai is a species of electric eel found in South America.

It is thought to have diverged from its sister species E. electricus during the Pliocene.

It is named in honor of the physicist Alessandro Volta, who is widely credited as the creator of the electric battery.

It has a maximum voltage of 860 volts, making it not only the strongest bioelectricity generator of the three electric eel species, but also of any animal.

A 2021 study reported the first known occurrence of pack hunting by electric eels in a population of E. voltai at the mouth of the Iriri River in Brazil.
