The burning of the Parliament Buildings in Montreal was an important event in pre-Confederation Canadian history and occurred on the night of April 25, 1849, in Montreal, the then-capital of the Province of Canada. It is considered a crucial moment in the development of the Canadian democratic tradition, largely as a consequence of how the matter was dealt with by then co-prime ministers of the united Province of Canada, Sir Louis-Hippolyte Lafontaine and Robert Baldwin.

Montreal is the largest city in the province of Quebec, the second-largest in Canada, and the tenth-largest in North America. Founded in 1642 as Ville-Marie, or "City of Mary", it is now named after Mount Royal, the triple-peaked hill around which the early settlement was built. The city is centred on the Island of Montreal and a few much smaller peripheral islands, the largest of which is Île Bizard. The city is 196 km (122 mi) east of the national capital, Ottawa, and 258 km (160 mi) southwest of the provincial capital, Quebec City.
