Ang aluminyo (Ingles: aluminum) ay isang elementong kimikal sa talahanayang peryodiko na sinasagisag ng simbolong Al at nagtataglay ng atomikong bilang 13.

(atomikong timbang = 26.98, punto ng pagkatunaw = 660.2 °C, punto ng pagkulo = 2,467 °C, ispesipikong grabidad = 2.69, V = 3, simbolo: Al, malaking A na sinundan ng maliit na L) ay isang metalikong elemento na maputi ang kulay at katulad ng pilak. Ito ang elementong itinuturing na pinakarami ang bilang sa balat ng lupa, bagaman natatagpuang nakalangkap sa iba pang mga elemento. Natuklasan ito ni Hans Christian Ørsted noong 1825. Ginagamit ito sa pag-gawa ng mga kasangkapang magagaan, hindi kalawangin, at matitibay o matitigas, katulad halimbawa ng sa kaldero at sa bubong ng bahay.^[10]
