Kaydyn (pronounced KAY-din) is a modern American respelling of Kayden/Caden, one of the -ayden family of names that rose in the late 1990s and 2000s alongside Aiden, Brayden, and Jayden. It is used as a unisex given name but skews masculine, and appears mostly in North America and, to a lesser extent, Australasia. As with many creative y-variants, Kaydyn emphasizes a contemporary look while preserving the familiar sound.

Behind the sound lies Caden/Kayden, likely from the Gaelic surname Mac Cadáin (“son of Cadan”), with Cadan linked to Old Irish cad, “battle,” or Welsh cad, “battle,” yielding senses like “fighter” or “battle-born.” Some modern bearers also associate it with the English word cadence, though this is folk etymology. Close variants include Kayden, Kaiden, Kaden, Caden, Cayden, Caiden, Kadyn, Kaidyn, Kaydin. Overall meaning: battle; warrior-like.
