Xerri's Grotto is a cave in Xagħra, Gozo, Malta. It was discovered by local resident Anthony Xerri in 1923 or 1924 while digging a well under a private house. Xerri's Grotto is not far from another underground feature, Ninu's Cave, which was discovered in 1888 in a similar fashion, when a well was being dug under a private house.
