The Apostolic Administration of Atyrau is a pastoral area sui iuris, not yet fully a diocese, in western Kazakhstan which forms part of the Roman Catholic Church in this country, namely of the metropolitan Roman Catholic Archdiocese of Mary Most Holy in Nur-Sultan.
Its head is a prelate called Apostolic Administrator, member of the Catholic Bishops’ Conference of Central Asia.[1] His see is the Cathedral of the Transfiguration of Our Lord, in Atyrau. Current Administrator is a Slovakian priest, Fr. Peter Sakmár. Former Apostolic Administrator, Italian Bishop Adelio Dell'Oro became the diocesan bishop of the Roman Catholic Diocese of Karaganda.[2]
Apostolic Administration of Atyrau was established by the Holy See on 7 July 1999 together with other three dioceses in Kazakhstan which formerly were one Apostolic Administration of Kazakhstan.
There are several churches in the main cities of Western Kazakhstan which belong to the Apostolic Administration of Aturau.[4]
