In chemistry, a superoxide is a compound that contains the superoxide ion, which has the chemical formula . The systematic name of the anion is dioxide(1−). The reactive oxygen ion superoxide is particularly important as the product of the one-electron reduction of dioxygen , which occurs widely in nature. Molecular oxygen (dioxygen) is a diradical containing two unpaired electrons, and superoxide results from the addition of an electron which fills one of the two degenerate molecular orbitals, leaving a charged ionic species with a single unpaired electron and a net negative charge of −

L'ion superoxyde, noté O2•− ou O2− (la deuxième écriture ne fait pas apparaître explicitement le caractère radicalaire) est issu de la réduction monoélectronique du dioxygène (O2). L'ion superoxyde est paramagnétique.
