The Italian Catholic Diocese of Civitavecchia-Tarquinia (Latin: Dioecesis Centumcellarum-Tarquiniensis) is in Lazio, and has existed under this name since 1986. The diocese is directly subject to the Holy See.
In 314 Epictetus, its bishop, was present at the Council of Arles. Another Epictetus, Bishop of Centumcellæ towards the middle of the fourth century, was an Arian and a counsellor of Emperor Constantius.
In 1086 the see was suppressed and Civitavecchia was united to the diocese of Toscanella, and in 1193 to the diocese of Viterbo. In 1825 Pope Leo XII re-established the see, uniting it to Porto and Santa Rufina.
In 1854 the union with Santa Rufina was severed and Civitavecchia was united with the diocese of Corneto. No bishops of Corneto are known for the ancient Christian period; it was made a diocese in 1435. Until 1986, the united diocese was known as Tarquinia e Civitaveccia .
