Pope John XVIII (Latin: Ioannes XVIII; died June or July 1009) was Pope and ruler of the Papal states from January 1004 (25 December 1003 NS) to his abdication in June 1009. He was born Giovanni Fassano at Rapagnano, near Ascoli Piceno, the son of a Roman priest, either named Leo according to the Catholic Encyclopedia, or named Ursus according to Horace K Mann.

During his whole pontificate he was allegedly subordinate to the head of the Crescentii clan who controlled Rome, the patricius (an aristocratic military leader) John Crescentius III.

This period was disrupted by continuing conflicts between the Ottonian Emperor Henry II and Arduin of Ivrea, who had styled himself King of Italy in 1002 after the death of Emperor Otto III. Rome was wracked with bouts of plague, and Saracens operated freely out of the Emirate of Sicily ravaging the Tyrrhenian coasts.

As Pope, John XVIII occupied his time mainly with details of ecclesiastical administration. He authorized a new Diocese of Bamberg to serve as a base for missionary activity among the Slavs, a concern of Henry II's. He also adjudicated a squabble between the abbot of Fleury and the bishops of Sens and Orléans. John was successful in creating, at least temporarily, a rapprochement between the Eastern and Western churches. His name could be found on Eastern diptychs and he was prayed for in masses in Constantinople.
