Robert Corrigan, (c. 1816 or 1817 – 19 October 1855) was an Irish-Canadian who was murdered by a group of men in Saint-Sylvestre, Lower Canada.
Corrigan followed the Catholic beliefs of his parents at the beginning of his life, but converted to Anglicanism at an unknown time.
He was disliked by the Irish community in the town because he had converted to Anglicanism and ridiculed the Catholics of his former faith.
His judging decisions at the fair angered the Irish townspeople and seven or eight people beat Corrigan with sticks.
Frustrated by the lack of arrests in December, the government sent a military detachment of 130 men to help in the search, but they were also unsuccessful.
When the resolution passed, the coalition government of Allan MacNab and Étienne-Paschal Taché refused to publish the instructions.
Faced with internal opposition from his political allies over this decision, MacNab resigned as premier and John A. Macdonald formed a new coalition government with Taché.
