The Great Fire of 8 July 1892 in St. John's, Newfoundland and Labrador is remembered as the worst disaster ever to befall that city. Previous "Great Fires" had occurred in St. John's, during 1819 and 1846.

St. John's is the capital and largest city of the Canadian province of Newfoundland and Labrador, located on the eastern tip of the Avalon Peninsula on the island of Newfoundland.

The city spans 446.04 km2 (172.22 sq mi) and is the easternmost city in North America (excluding Greenland).Its name has been attributed to the belief that John Cabot sailed into the harbour on the Nativity of John the Baptist in 1497. Another possibility is that it is named after a Basque fishing town with the same name. Existing on maps as early as 1519, it is one of the oldest cities in North America. It was officially incorporated as a city in 1888. With a metropolitan population of approximately 212,579 (as of February 9, 2022), the St. John's Metropolitan Area is Canada's 20th-largest metropolitan area and the second-largest Census Metropolitan Area (CMA) in Atlantic Canada, after Halifax.The city has a rich history, having played a role in the Seven Years' War, the American Revolutionary War, and the War of 1812. Italian inventor Guglielmo Marconi received the first transatlantic wireless signal in St. John's. Its history and culture have made it into an important tourist destination. St. John's was referred to as Baile Sheáin (Johnstown), in the poetry of Donnchadh Ruadh Mac Conmara (1715–1810), and among speakers of the Irish language in Newfoundland.
