Meliadus is Celtic in Origin.

Meliadus is a masculine given name from medieval Arthurian romance, chiefly Old French. It identifies the chivalric figure Méliadus de Leonois, king of Lyonesse and father of Tristan, prominent in the 13th-century Prose Tristan and in the Guiron/Palamedes cycle (often titled Roman de Méliadus). The name entered Middle English tradition via Thomas Malory, where King Meliodas appears in Le Morte Darthur, helping fix the form in later retellings.

Its etymology is uncertain; most editors regard Meliadus/Meliodas as a literary formation within Old French, perhaps colored by Celtic toponymy, with no securely recoverable meaning. Medieval and later spellings vary: Méliadus, Meliaduz, Méliadus de Leonois; English Meliodas, Mellyodas; Latinized Meliodus. Related forms such as Meliador in separate romances are parallel rather than direct variants. Modern given-name usage is extremely rare, though Meliodas has pop-cultural visibility, indirectly preserving this archaic Arthurian name.
