奥斯坎语是奥斯坎人所操的语言，它是属于印欧语系意大利语族萨贝利克语支的，同语支的还有拉丁-法利希语和翁布里亚语，奥斯坎人分布于萨莫奈、坎帕尼亚、卢卡尼亚、阿布鲁索。奥斯坎语因公元前五世纪初的牌铭而闻名，其中两个最重要的牌铭是：班迪纳牌铭和赛普斯·阿贝拉努斯牌铭。奥斯坎语使用的是拉丁字母和希腊字母，同时也曾使用过古意大利字母。

奥斯坎语有六种方言，包括：萨姆尼特方言，马鲁齐内方言，贝利涅方言，维斯蒂尼方言，萨比内方言，马尔斯方言。

奥斯坎语与拉丁语有许多共同点，但也有许多显著区别，很多常见拉丁语词组缺失并使用完全不同的词来。例如：拉丁语的volo,velle,volui,和来自普鲁东-印欧语系的词根wel(将，会)，奥斯坎语里就是缘自*gher的herest(他想，他希望)，与拉丁语的vult完全不同，又如「地方、位置」一词，拉丁语是locus，奥斯坎语是slaagid。

Not to be confused with Old Scandinavian, sometimes abbreviated 'OScan'.

Oscan is an extinct Indo-European language of southern Italy. The language is also the namesake of the language group to which it belonged. As a member of the Italic languages, Oscan is therefore a sister language to Latin and Umbrian.

Oscan was spoken by a number of tribes, including the Samnites, the Aurunci (Ausones), and the Sidicini. The latter two tribes were often grouped under the name "Osci". The Oscan group is part of the Osco-Umbrian or Sabellic family, and includes the Oscan language and three variants (Hernican, Marrucinian and Paelignian) known only from inscriptions left by the Hernici, Marrucini and Paeligni, minor tribes of eastern central Italy. The language was spoken from approximately 500 BC to AD 100.
