Cornelius O'Callaghan (1809 – 16 August 1849) of Shanbally Castle, Clogheen, Co. Tipperary, was an Irish politician. He sat in the House of Commons of the United Kingdom as a Member of Parliament (MP) for Tipperary from 1832 to 1835, and for Dungarvan from 1837 to 1841. Shanbally Castle was built for his father, Cornelius O'Callaghan, 1st Viscount Lismore who outlived him, so his brother George inherited the title and estate.
