SS Noronic was a passenger ship that was destroyed by fire in Toronto Harbour in September 1949 with the loss of at least 118 lives.

SS Noronic was launched June 2, 1913, in Port Arthur, Ontario, Canada. She was built by the Western Dry Dock and Shipbuilding Company for the Northern Navigation Company, an operating division of Richelieu and Ontario Navigation Company, to perform passenger and package freight service on the Great Lakes. She had five decks, was 362 feet (110 m) in length, and measured 6,095 gross register tons. At maximum capacity, she could hold 600 passengers and 200 crew. One of the largest and most beautiful passenger ships in Canada at the time, she was nicknamed “The Queen of the Lakes."

Passenger decks were labelled A, B, C, and D, and none had direct gangplank access to the dock. The only exits were located on the lowest deck, E deck. There were two gangplanks on the port side and two on the starboard side, and only two were operational at a time.

Noronic had eight fleetmate ships: City of Midland, Doric, Germanic, Ionic, Majestic, Waubic, Huronic and Hamonic. Hamonic burned in 1945 and Huronic was retired and scrapped in 1950.
