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]

  1. Davy's 1812 written usage of the word aluminum was predated by other authors' usage of aluminium. However, Davy is often mentioned as the person who named the element; he was the first to coin a name for aluminium: he used alumium in 1808. Other authors did not accept that name, choosing aluminium instead. See below for more details.
