The Old Catholic Church of Austria is the Austrian member church of the Old Catholic Churches' Union of Utrecht. It was nationally recognized in 1877, despite objections of the imperial dynasty and the Roman Catholic hierarchy in the formally pro-Vatican I state of Austria-Hungary.
In 1997, the church began ordaining women. In 2007, the church elected Bishop John Okoro. Bishop Okoro was born in Nigeria and was ordained as a priest in the Roman Catholic Church, but joined the Old Catholic Church of Austria in 1999. Prior to his election he had been the parish priest in Vorarlberg.
