Lieutenant-Colonel Samuel H. S. Hughes, QC (1913–2002) was a Canadian lawyer who served as a justice of the Supreme Court of Ontario. He had a less well-known background as a Canadian military historian during the Second World War.
Shortly after retiring as a judge he took on the task of chairing a Royal Commission known as the Hughes Inquiry into allegations of child abuse by members of the Christian Brothers of Ireland at Mount Cashel Orphanage in Newfoundland.
