Meaning & Origin
Kayleb is a boy's baby name of Hebrew origin, a phonetic variant spelling of Caleb, meaning 'devotion to God' or 'faithful, bold.' In the Old Testament, Caleb was one of only two scouts who brought back a confident report from Canaan, earning him a place among those who entered the Promised Land.
Kayleb takes the solid biblical heritage of Caleb and wraps it in a contemporary spelling that appeals to parents who want the name's faithful character with a modern visual twist. With nearly 2,400 recorded births, it has real momentum — reflecting how classic names can be reinvented while keeping their soul intact.
