The Adamic language, according to Jewish tradition (as recorded in the midrashim) and some Christians, is the language spoken by Adam (and possibly Eve) in the Garden of Eden. It is variously interpreted as either the language used by God to address Adam (the divine language), or the language invented by Adam with which he named all things (including Eve), as in the second Genesis creation narrative (Genesis 2:19).

In the Middle Ages, various Jewish commentators held that Adam spoke Hebrew, a view also addressed in various ways by the late medieval Italian poet Dante Alighieri. In the early modern period, some authors continued to discuss the possibility of an Adamic language, some continuing to hold to the idea that it was Hebrew, while others such as John Locke were more skeptical. More recently, a variety of Mormon authors have expressed various opinions about the nature of the Adamic language.

According to Ethiopian and Eritrean traditions, the ancient Semitic language of Ge'ez is the language of Adam. Southern Semitic languages spoken in Ethiopia and Eritrea are older than Northern Semitic languages, such as Hebrew. Semitic languages were spoken in Eritrea from approximately 2000 BC.
