Rafael Kayanan is a Filipino-born naturalized American comics artist and Filipino martial arts master in the Sayoc Kali system.

Rafael Kayanan stated in a 2007 interview that he "grew up with Filipino Komiks masters like Alcala, Coching, and Redondo mixed in with Kirby, Sy Barry's The Phantom, Kubert's Tarzan, and Hal Foster's Prince Valiant. From there I discovered Barry Windsor-Smith, Starlin, Adams, Wrightson, and Gulacy in the 70's. I copied and then drew my own stories on the backs of old xeroxes my mom would bring home from work."

He has illustrated for every major comic book publisher. His most notable work has been on Marvel Comics' Conan the Adventurer, Acclaim Comics' Turok, and DC Comics' Fire...
