John XV (born in Rome), Pope from 985 to 996, succeeding Boniface VII (974, 984–985). It was said to have been Pope after another Pope John that reigned four months after Pope John XIV (983–984) and was named "Papa Ioannes XIV Bis" or "Pope John XIV Two". This John XIV Two never existed, because he was confused with a certain cardinal deacon John son of Robert that opposed to Boniface VII, and now is excluded from the papal lists.
