Silvio Celestino Corio (28 October 1875 – 11 January 1954), also called Crastinus,{{Cite book|last=Dupuy|first=Pascal|title=Folgorite, parcours de Sante Ferrini, anarchiste, typographe et poète (1874-1939)|publisher=Atelier de création libertaire|year=2020|location=Lyon}} was an Italian anarchist who was active in London during the first half of the twentieth century.

Silvio was born in Turin, the son of Eugenio Corio and Chiara Domenica. Following some initial involvement with the Turin Socialist Club, he became active as an anarchist. He trained as a printer and typographer. He was conscripted in July 1897 and spent most of the next 18 months in a disciplinary battalion as a result of his political activity. However, in 1898 he fled to France in the face of the repression implemented by Prime Minister Luigi Pelloux.{{cite web|last1=Heath|first1=Nick|title=Corio, Silvio (1875–1954) aka Crastinus, Qualunque|url=https://libcom.org/history/corio-silvio%C2%AC%C2%AC-1875-1954-aka-crastinus-qualunque|website=Lib Com|publisher=Lib Com|accessdate=20 September 2015}}
