David Ellis (31 August 1736 – 1795) was a Welsh Anglican clergyman, poet and transcriber of manuscripts.
After attending the school in Ystrad Meurig, he studied at Jesus College, Oxford, but only from March to June 1764.
In the following year, he became vicar of Criccieth, holding the post until his death.
In addition to his clerical duties, Ellis wrote poetry and translated works by others from English into Welsh.
He also transcribed many Welsh manuscripts, some of which are now preserved in the National Library of Wales.
