Church Slavonic, also known as Church Slavic, New Church Slavonic or New Church Slavic, is the conservative Slavic liturgical language used by the Orthodox Church in Bulgaria, Poland, the Czech Republic and Slovakia, Russia, Serbia, Montenegro, Bosnia and Herzegovina, the Republic of Macedonia and Ukraine. The language also occasionally appears in the services of the Orthodox Church in America. It was also used by the Orthodox Churches in Romanian lands until the late 17th and early 18th centuries, as well as by Roman Catholic Croats in the early Middle Ages.

In addition, Church Slavonic is used by some churches which consider themselves Orthodox but are not in communion with the Orthodox Church, such as the Macedonian Orthodox Church, the Montenegrin Orthodox Church, the Russian True Orthodox Church and others. It is also sometimes used by Greek Catholic Churches, which are under Roman communion, in Slavic countries, for example the Croatian and Ruthenian Greek Catholics, as well as by the Roman Catholic Church (Croatian and Czech recensions, see below).
