Vom chemischen Element Aluminium sind 22 Isotope und mehrere Kernisomere bekannt. In der Natur treten das stabile Isotop 27Al (fast 100 %) und das Radioisotop 26Al (in Spuren, Halbwertszeit ca. 720000 Jahre) auf. Alle anderen Isotope sind instabil mit kleinen Halbwertszeiten von unter 7 Minuten oder weit darunter.
