Arebica is a Bosniak variant of the Arabic script used to write the Bosnian language. It was used mainly between the 15th and 19th centuries and is frequently categorized as part of Aljamiado literature. Before World War I there were unsuccessful efforts by Bosnian Muslims to adopt Arebica as the third official alphabet for Bosnian alongside Latin and Cyrillic.

Bosnian Cyrillic, widely known as Bosančica is an extinct variant of the Cyrillic alphabet that originated in medieval Bosnia. The term was coined at the end of the 19th century by Ćiro Truhelka. It was widely used in modern-day Bosnia and Herzegovina and the bordering areas of modern-day Croatia. Its name in Bosnian-Croatian-Serbian is Bosančica and Bosanica the latter of which can be translated as Bosnian script. Serb scholars call it Serbian script, Serbian–Bosnian script, Bosnian–Serb Cyrillic, as part of variant of Serbian Cyrillic and the term "bosančica" according to them is Austro-Hungarian propaganda. Croat scholars also call it Croatian script, Croatian–Bosnian script, Bosnian–Croat Cyrillic, harvacko pismo, arvatica or Western Cyrillic. For other names of Bosnian Cyrillic, see below.

Standard Bosnian, Croatian, Montenegrin, and Serbian are different national variants and official registers of the pluricentric Serbo-Croatian language.
