The SS Marquette & Bessemer No. 2 was a train ferry that sank with the loss of between 30 and 38 lives on Lake Erie on December 8, 1909.

Built in Cleveland, Ohio in 1905, the SS Marquette & Bessemer No. 2 was a train ferry built to transport railway cars across Lake Erie from Conneaut, Ohio, to Port Stanley, Ontario. She had a length of 338 feet (103 meters) and a beam of 54 feet (16.5 meters), and her gross register tonnage was 2,514. The second of two ships built for and named after the Marquette & Bessemer Dock & Navigation Company, she was commonly referred to as "The Car Ferry" by the residents of Conneaut, while Marquette & Bessemer No. 1 was known as "The Collier," as her cargo was always railway cars filled with coal.

At 10:43 on the morning of December 7, 1909, the Marquette & Bessemer No. 2 departed Conneaut for its daily 5-hour run to Port Stanley. The cargo was made up of thirty loaded railway cars (26 of coal, three of steel beams, and one of iron castings). Departure had been delayed due to an ore carrier's lines having parted in the strong winds, and it took nearly three hours before the harbor tugs had pushed the ship back against the dock. The wind was blowing out of the southwest, gusting to 50 mph when the Marquette & Bessemer No. 2 left Conneaut, and by that evening it had reached sustained winds of 75 mph.
