Ang titanyo o titanyum (Espanyol: titanio, Ingles: titanium) ay ang pangdalawangput-dalawa na elementong kimikal sa talaang peryodiko. Ang simbolo nito ay Ti at nagtataglay ng bilang atomiko na 22. Ito ay nangangalawa sa mga transisyong metal ng talaang peryodiko. Ito ay matibay, magaan, makisap at maputing elementong metaliko na matibay sa korosyon. Ginagamit sa pag-gawa ng mga piyesa ng eroplano at mga kasangkapang matibay sa init. Natuklasan noong 1791 ni W Gregor.
