Montenegrin is a South Slavic language spoken primarily in Montenegro. It is one of the standard varieties of the Serbo-Croatian language and shares mutual intelligibility with Serbian, Croatian, and Bosnian. Montenegrin is officially recognised as the national language of Montenegro, and it uses both the Latin and Cyrillic alphabets, though the Latin script is more commonly used in modern times.

The language has undergone standardisation efforts to distinguish it from other Serbo-Croatian varieties, incorporating specific phonetic and lexical differences. While there is debate regarding its status as a separate language or a variant of Serbian, Montenegrin remains an essential part of national identity. It is used in government, media, and education, with ongoing efforts to preserve and develop its linguistic uniqueness.
