The Synod of Kells took place in AD 1152, under the presidency of Cardinal Paparoni, and continued the process begun at the Synod of Rathbreasail of reforming the Irish church. The sessions were divided between the abbeys of Kells and Mellifont, and in later times the synod has been called the Synod of Kells-Mellifont and the Synod of Mellifont-Kells.
