The Impiso Cave () is a sea cave located in San Felice Circeo, Italy.
The cave is located along the coast on the southern side of Mount Circeo in the comune of San Felice Circeo. Situated a few dozen meters west of the Goats Cave, it can only be accessed by sea.
It is so called because of the presence of a large stalactite hanging from the ceiling of its vault, which resembles a hanged man, translated as impiso in Italian.
