Il curio è l'elemento chimico della tavola periodica degli elementi che ha come simbolo Cm e come numero atomico 96. È un metallo radioattivo transuranico della serie degli attinidi; è prodotto per bombardamento del plutonio con particelle alfa (che sono ioni di elio) e prende il nome dai coniugi Marie e Pierre Curie.
