Kaiden is a modern given name of recent origin, first gaining popularity in the early 2000s. Its roots can be traced back to two distinct sources: the Irish surname 'Keady', which is derived from the Irish Gaelic name 'Caoidhe' meaning 'handsome' or 'comely'; and the English surname 'Kayden', a variant of 'Caden' which is derived from the Welsh given name 'Cadien', also meaning 'battle'.
