Bosnian Cyrillic, widely known as Bosančica is an extinct variant of the Cyrillic alphabet that originated in medieval Bosnia. It was widely used in modern-day Bosnia and Herzegovina and the bordering areas of modern-day Croatia (southern and middle Dalmatia and Dubrovnik regions). It was particularly used by the Bosnian Church community. Its name in Serbo-Croatian is bosančicaand bosanica the latter of which can be translated as Bosnian script. Serbian scholars consider it as part of variant of Serbian Cyrillicbecause of a lot of mentions of Bosnian Cyrillic as Serbian letters or Serbian characters in sources among Catholics and Muslims in Bosnia and Southern Dalmatia.Croat scholars also call it Croatian script, Croatian–Bosnian script, Bosnian–Croat Cyrillic, harvacko pismo, arvatica or Western Cyrillic.

The use of Bosančica amongst Bosnians was replaced by Arebica upon the introduction of Islam in Bosnia Eyalet, first amongst the elite, then amongst the wider public. The first book in Bosančica was printed by Frančesko Micalović in 1512 in Venice.
