Niķelis ir ķīmiskais elements ar simbolu Ni un atomskaitli 28. Dabā niķelis galvenokārt ir sastopams kā piemaisījums dzelzsrūdām. Niķelis ir korozijas izturīgs metāls, kuru lieto pārklājumiem (lai aizsargātu pret koroziju) un dzelzs sakausējumos (nerūsējošais tērauds). Nikeļa savienojumi parasti ir gaiši zaļi. Savienojumos niķelim parasti ir oksidācijas pakāpe +2.
