Keyn is in Origin.

Keyn is a rare Celtic given name. In Welsh and Cornish tradition it is an Anglicized form of Cein/Keyne, borne by the 5th‑century Saint Keyne, daughter of Brychan, whose cult and holy well are commemorated in Cornwall and South Wales. In Welsh, cain/cein means “fair, beautiful, fine,” yielding the sense “beautiful” or “of fair form.” While the saint is female, the concise shape and surname-like look make Keyn usable for any gender today. Usual pronunciation is KAYN.

In modern records Keyn appears sporadically in Britain and the wider Anglosphere. Some bearers may intend it as a streamlined variant of Keyne, while others treat it as a creative respelling influenced by Irish Cian/Kian (“ancient, enduring”) or by the English surname Keene (from Old English cēne, “bold, brave”). Related forms and variants include Keyne, Cein, Ceinwen, Cain (Welsh), Cian, Kian, Keane, Kean, and Keene; short forms include Key/Kei.
