Dillon is Welsh in Origin.

With twin roots, Dillon is both an Irish surname and a modern given-name spelling linked to Welsh Dylan. The surname stems from Norman French de Léon (“from Léon,” a region of Brittany) brought to Ireland in the 12th century, where the Dillon family became prominent nobles. As a first name, Dillon commonly riffs on Dylan from medieval Welsh legend - Dylan ail Don - whose name is analyzed as dy “great” + llanw “tide,” yielding the sea-tinged sense “great tide” and popularly “son of the sea.”

Usage surged in the Anglophone world from the 1980s–2000s, especially in the United States and Ireland, paralleling the rise of Dylan; pop-culture visibility aided recognition. Variant spellings include Dylan, Dyllan, Dilan, Dillen, and Dillion; Dillon remains the most established surname form. While primarily masculine, it is occasionally used for girls. Note that Dhillon, common in Punjabi communities, is an unrelated surname.
