Cayden is one of many spellings of Caden, a name that rose in the 1990s as a rhyme to Aiden, Jayden and Braden; it is usually traced to the Irish surname Mac Cadáin, "son of Cadán", a name linked to cath, "battle". The C spelling with a y is a purely American touch. Cayden peaked at number 143 in 2009 and has slid to number 414 in 2025, as the whole rhyming family has cooled off.
