John XV (Latin: Ioannes PP.

XV, Italian: Giovanni XV; born in Rome, died March 996) is Pope from 985 to 996, succeeding Boniface VII.

He is said to have been Pope after another Pope John who reigned four months after Pope John XIV (983–984) and was named "Papa Ioannes XIV Bis" or "Pope John XIVb".

This supposed first John XIV never existed, rather he was confused with a certain cardinal deacon John, son of Robert, who was opposed to Boniface VII and is now excluded from the papal lists.
