Angtitanyo otitanyum (Kastila:titanio,Ingles:titanium) ay ang pangdalawangput-dalawa naelementong kimikal satalaang peryodiko. Ang simbolo nito ayTi at nagtataglay ng bilang atomiko na 22. Ito ay nangangalawa sa mgatransisyong metal ngtalaang peryodiko.Ito ay matibay, magaan, makisap at maputing elementong metaliko na matibay sa korosyon. Ginagamit sa pag-gawa ng mga piyesa ngeroplano at mga kasangkapang matibay sa init. Natuklasan noong 1791 ni W Gregor.
