The short answer
Kayden is a modern English name, pronounced KAY-dən, which Behind the Name records simply as a variant of Caden. The Caden entry is candid that the name is "sometimes explained" as coming from the Irish surname Caden (from the given name Cadán, "of unknown meaning"), but that its popularity in America from the 1990s is really down to its sound: it shares a fashionable -den ending with Hayden, Aidan and Braden. So Kayden has no settled meaning; it is a sound-driven spelling of a sound-driven name. In the United States it ranked #135 for boys in 2025.
Meaning and etymology
Behind the Name's Kayden entry reads, in full, "Variant of Caden", and lists the roots as the phonetic elements kay + den. The parent entry for Caden explains that the name is "sometimes explained as deriving from the Irish surname Caden, which is an Anglicized form of Irish Gaelic Mac Cadáin, itself from the given name Cadán (of unknown meaning)", and then adds: "In actuality, the popularity of this name in America beginning in the 1990s is due to its sound", pointing to the den suffix it shares with Hayden, Aidan and Braden. Kayden therefore has no verified gloss; the Irish-surname explanation is reported as a common account, not an established etymology.
