Kayden is a modern name whose origin is not settled. It is usually treated as a spelling variant of Kaden, and standard dictionaries generally trace that form to the Irish surname Mac Cadáin, meaning son of Cadán. Cadán may come from the Gaelic cad, battle, though the precise meaning is uncertain. Kayden itself has no long separate history; it is best described as a modern American coinage or variant rather than a traditional name with a fixed translation.
Kayden is pronounced KAY-dən, with the stress on the first syllable and a schwa in the second. American and British English give it the same pronunciation.
The name has few traditional associations. A notable bearer is Kayden Troff, an American chess grandmaster who won the World Under-14 Chess Championship in 2012. Kayden has no established place in literature, history or religion.
In the United States, Kayden was rare before the 1990s: in 1989 only 6 boys received it. It rose quickly, entered the top 100 in 2012 and peaked at No. 90 in 2014, when 4,742 boys were given the name. By 2025 it ranked No. 135, with 2,678 births, so it remains fairly common but has declined from its peak.
