The Croatian Orthodox Church (Croatian: Hrvatska pravoslavna crkva) was a religious body created during World War II by the Fascist Ustaše regime in the Independent State of Croatia (NDH). It was created in order to assimilate the remaining Serb minority and also to unite other Orthodox communities into a state-based Greek Orthodox Church.
In 1942, NDH authorities finally made a move to organize a domestic Orthodox Church. This was part of a policy to eliminate Serb culture from Axis Croatia. The church lasted from 1942–45, and was intended to serve as a national church to which Serbs living in Croatia would convert, thus making it possible to describe them as "Croats of Orthodox faith". The Croatian Orthodox Church was managed by Montenegrin nationalist Savić Marković Štedimlija. There were some discussions during the 1990s, after the breakup of Yugoslavia, regarding the revival of such a church.
