The Paleo-Hebrew script, also Palaeo-Hebrew, Proto-Hebrew or Old Hebrew, is the writing system found in inscriptions of Canaanite languages from the region of Southern Canaan, also known as biblical Israel and Judah. It is considered to be the script used to record the original texts of the Hebrew Bible due to its similarity to the Samaritan script, as the Talmud stated that the Hebrew ancient script was still used by the Samaritans. The Talmud described it as the "Libona'a script", translated by some as "Lebanon script". Use of the term "Paleo-Hebrew alphabet" is due to a 1954 suggestion by Solomon Birnbaum, who argued that "[t]o apply the term Phoenician [from Northern Canaan, today's Lebanon] to the script of the Hebrews [from Southern Canaan, today's Israel-Palestine] is hardly suitable". The Paleo-Hebrew and Phoenician alphabets are two slight regional variants of the same script.

Hebrew is a Northwest Semitic language within the Afroasiatic language family. A regional dialect of the Canaanite languages, it was natively spoken by the Israelites and remained in regular use as a first language until after 200 CE and as the liturgical language of Judaism and Samaritanism. The language was revived as a spoken language in the 19th century, and is the only successful large-scale example of linguistic revival. It is the only Canaanite language, as well as one of only two Northwest Semitic languages, with the other being Aramaic, still spoken today.
