The transition of church communities to the OCU is the process of transition of parishes, previously affiliated to the Ukrainian Orthodox Church (Moscow Patriarchate) (UOC MP), from that metropolis to the Orthodox Church of Ukraine (OCU).

In general, in four years after the unification council, almost 1,500 religious communities joined the OCU.
