The Sword of Saint Peter (Polish: Miecz świętego Piotra) is a religious relic held in the Poznań Archdiocesan Museum.
It is claimed to be the sword with which the Apostle Peter cut off the right ear of the high priest's servant at the time of Jesus' arrest in Gethsemane.
An exact copy of the sword, made by Bogdan Puchalski, is displayed on the wall of the Poznań Archcathedral Basilica.
The sword arrived in Poznań in 968 as a gift from John XIII for either Bishop Jordan or Duke Mieszko I.
According to British folklore, St. Joseph of Arimathea brought the sword to Britain, and it was kept at Glastonbury Abbey for many years until the abbot gave it to Saint George.
