Aron Pumnul (November 27, 1818 Cuciulata, district of Braşov - January 12/24, 1866, Chernivtsi) was a Romanian philologist and teacher, national and revolutionary activist in Transylvania and later in Bucovina (then in the Habsburg Monarchy).
He was the subject of the poem "La mormântul lui Aron Pumnul" (At the Grave of Aron Pumnul) by Mihai Eminescu.
In the field of linguistics, he supported the adoption of Latin alphabet instead of the Cyrillic alphabet, but he opposed direct loanwords from other Romance languages, promoting instead the Romanianization of the language, through the creation of words using Romanian roots (for instance vorbământ for etymology and tâmplământ for history) or importing Latin words by passing them through the phonetic changes from Latin to Romanian.
