Anglesey (ANG-gəl-see) is an English toponymic name taken from the large island and county off northwest Wales. The English form most likely comes from Old Norse Ǫngulsey, “Ongull’s island,” from the personal name Ǫngull + ey “island,” though some scholars interpret it as “Angles’ island,” linking it to the Germanic Angles. Its Welsh counterpart is Ynys Môn - known to the Romans as Mona - rooted in ancient Brittonic and celebrated in the epithet Môn Mam Cymru, “Môn, mother of Wales.”

Used historically as a surname and noble title (notably the Marquess of Anglesey), it has only recently appeared as a rare given name in the English-speaking world.
