The Canaanite languages, or Canaanite dialects, are one of three subgroups of the Northwest Semitic languages, the others being Aramaic and Amorite, all originating in the Levant and Mesopotamia. They are attested in Canaanite inscriptions throughout the Levant, Mesopotamia, Anatolia and the East Mediterranean, and after the founding of Carthage by Phoenician colonists, in coastal regions of North Africa and Iberian Peninsula also. Dialects have been labelled primarily with reference to Biblical geography: Hebrew (Israelian, Judean/Biblical, Samaritan), Phoenician/Punic, Amorite, Ammonite, Moabite, Sutean and Edomite; the dialects were all mutually intelligible, being no more differentiated than geographical varieties of Modern English. This family of languages has the distinction of being the first historically attested group of languages to use an alphabet, derived from the Proto-Canaanite alphabet, to record their writings, as opposed to the far earlier Cuneiform logographic/syllabic writing of the region, which originated in Mesopotamia.

These extremely closely related tongues were spoken by the ancient Semitic-speaking peoples of Canaan and Levant, an area encompassing what is today Israel, Jordan, the Sinai Peninsula, Lebanon, Syria, Palestine, and also some areas of southwestern Turkey (Anatolia), western and southern Iraq (Mesopotamia) and the northwestern corner of Saudi Arabia.

The Canaanites are broadly defined to include the Hebrews (including Israelites, Judeans and Samaritans), Amalekites, Ammonites, Amorites, Edomites, Ekronites, Hyksos, Phoenicians (including the Carthaginians), Moabites and Suteans. Although the Amorites are included among the Canaanite peoples, their language is sometimes not considered to be a Canaanite language but very closely related.

The Canaanite languages continued to be everyday spoken languages until at least the 2nd century AD. Hebrew is the only living Canaanite language today. It remained in continuous use by many Jews well into the Middle Ages and up to the present day as both a liturgical and literary language and was used for commerce between disparate diasporic Jewish communities. It has also remained a liturgical language among Samaritans. Hebrew was revived by Jewish political and cultural activists, particularly through the revitalization and cultivation efforts of Zionists throughout Europe and in Palestine, as an everyday spoken language in the late 19th and early 20th centuries. By the mid-20th century, Modern Hebrew had become the primary language of the Jews of Palestine and was later made the official language of the State of Israel.

The primary modern reference book for the many extra-biblical Canaanite inscriptions, together with Aramaic inscriptions, is the German-language book Kanaanäische und Aramäische Inschriften, from which inscriptions are often referenced as KAI n (for a number n).
