Il nichel (o nichelio) è l'elemento chimico di numero atomico 28 e il suo simbolo è Ni. È il primo elemento del gruppo 10 del sistema periodico, facente parte del blocco d, ed è quindi un elemento di transizione. Nella vecchia nomenclatura ha costituito, insieme al ferro e al cobalto la triade del gruppo VIII del sistema periodico, detto anche gruppo del ferro; allo stato metallico condivide con essi il ferromagnetismo, sebbene meno spiccato che nel ferro. Il nome deriva dallo svedese Nickel, diminutivo di Nikolaus, anticamente associato a persona da poco, folletto o ragazzo irrequieto, troppo pieno di vitalità. Esiste poi il derivato tedesco Kupfernickel ("rame del diavolo"), nome dato dai minatori che, cercando il rame, trovavano invece questo elemento e ne davano la colpa a un genio maligno.
