The Forum Piscarium was the fish forum venalium of ancient Rome, north of the Roman Forum, between the Capitoline hill and the Tiber, in the area of the current Roman Ghetto. It was burned in 210 BC and rebuilt the next year. In 179 it was incorporated in the general Macellum , built by Fulvius Nobilior in the same region.

This forum is called piscatorium in Livy, and piscarium in Varro and Plautus (Curc. 474).
