Tifinagh (pronounced: [tifinaɣ], also written Tifinaɣ in the Berber Latin alphabet, ⵜⵉⴼⵉⵏⴰⵖ in Neo-Tifinagh, and تيفيناغ in the Berber Arabic alphabet) is a series of abjad and alphabetic scripts used by some Berber peoples, notably the Tuareg, to write their language.

A modern derivate of the traditional script, known as Neo-Tifinagh, was introduced in the 20th century. It is not in widespread use as a means of daily communication, but often serves to assert a Berber identity politically and symbolically. A slightly modified version of the traditional script, called Tifinagh Ircam, is used in a limited number of Moroccan elementary schools in teaching the Berber language to children.

The word tifinagh or tifinigh is widely thought to be a feminine plural cognate of Punic, through the feminine prefix ti- and Latin Punicus; thus tifinigh would mean "the Phoenician (letters)".

An early form of the script, "Proto-Tifinagh", also known as the Libyco-Berber script, probably developed from the Punic variant of the Phoenician alphabet. Proto-Tifinagh was in use between about the 3rd century BC and the 3rd century AD.
