Meirion is Welsh in Origin.

Meirion is a Welsh masculine given name rooted in the Brythonic tradition, closely associated with the old cantref of Meirionnydd (Merioneth). Medieval genealogies record Meirion ab Tybion, a son of Cunedda, as the eponymous founder whose name gave the district its identity, anchoring the name in early Welsh royal lore. After centuries of sporadic use, Meirion re-emerged during the 19th–20th-century Welsh cultural revival and today remains recognizably Welsh, borne by figures such as composer Meirion Williams and poet Meirion Pennar.

Its precise etymology is debated: some scholars see a link to Latin Marianus ("of Marius," "devoted to Mars"), adapted into Welsh, while others treat it chiefly as the personal name behind Meirionnydd. Either way, it carries a strong sense of place and heritage. Variants and related forms include the Anglicized Merion and the short form Mei; a rare feminine elaboration Meiriona occasionally appears.
