This is a list of terminology used in the fictional Dune universe created by Frank Herbert, the primary source being "Terminology of the Imperium," the glossary contained in the novel Dune (1965).

Dune word construction could be classified into three domains of vocabulary, each marked with its own neology: the names and terms related to the politics and culture of the Galactic Empire, the names and terms characteristic of the mystic sodality of the Bene Gesserit, and the barely displaced Arabic of the Fremen language. Fremen share vocabulary for Arrakeen phenomena with the Empire, but use completely different vocabulary for Bene Gesserit-implanted messianic religion.

Due to the similarities between some of Herbert's terms and ideas and actual words and concepts in the Arabic language — as well as the series' "Islamic undertones" and themes — a Middle Eastern influence on Herbert's works has been noted repeatedly.
