The Old Hungarian script or Hungarian runes is an alphabetic writing system used for writing the Hungarian language. Modern Hungarian is written using the Latin-based Hungarian alphabet. The term "old" refers to the historical priority of the script compared with the Latin-based one. The Old Hungarian script is a child system of the Old Turkic alphabet.
