Keen is a modern English given name drawn from the common adjective meaning “sharp, eager, perceptive.” The word ultimately traces to Old English cēne “bold, brave,” whose sense shifted over time from courage to acuity. As a transferred surname, Keen/Keene developed from the same nickname for a spirited person and, in some families, represents an Englishing of Irish Keane/Kane from Ó Catháin, connecting the name to cath “battle” and to the personal name Cathán.

Used sporadically as a first name since the late 19th century in the Anglophone world, Keen remains uncommon but has seen modest contemporary use, fitting the modern preference for concise, punchy names. It is largely masculine but works as gender-neutral. Variants and related forms include Keene, Kean, and Keane; Kane is a cousin. Not to be confused with Kian (Irish Cian, “ancient”).
