Myles Patrick Dillon (11 April 1900 – 18 June 1972) was an Irish scholar whose primary interests were comparative philology, Celtic studies, and Sanskrit.

[3] Myles Dillon graduated from University College Dublin, and then travelled to Germany and France, where he studied in deep Old Irish and Celtic philology under Joseph Vendryes and Rudolf Thurneysen.

Among his most notable works are The Cycles of the Kings (1946), Early Irish Literature (1948), The Celtic Realms (1967, with Nora Kershaw Chadwick).

He also translated Dieux et héros des Celtes by Marie-Louise Sjoestedt into English, thus making the book available for a wider scholarly audience.

The monograph Celts and Aryans, published posthumously by the Indian Institute of Advanced Study reflects Dillon's interest in the traces of the shared heritage in the Indian and Irish cultures deriving from Proto-Indo-European society based on a period of research Dillon spent in Simla, India.
