SS Arctic, an American paddle steamer owned by the Collins Line, sank on September 27, 1854, 50 miles (80 km) off the coast of Newfoundland after a collision with SS Vesta, a much smaller French vessel. Passenger and crew lists indicate that there were probably more than 400 on board; of these, only 88 survived, most of whom were members of the crew. All the women and children on board perished.

Arctic was the largest and most celebrated of the four Collins steamers that had operated a regular transatlantic passenger and mail carrying service since 1850. After the collision her captain, James Luce, first attempted to assist the stricken Vesta, which he believed was in imminent danger of sinking. When he discovered that his own ship had been seriously holed below the waterline, he decided to run her towards the nearest land in the hopes of reaching safety. His plan failed; the engines stopped when the ship was still a considerable distance from land. Arctic's lifeboat capacity was sufficient for fewer than half of those on board; when Luce ordered these launched, a breakdown in order and discipline meant that most places in the boats were taken by members of the crew or the more able-bodied male passengers. The rest struggled to build makeshift rafts, but most were unable to leave the ship and went down with her when she sank, four hours after the collision. Vesta, which initially appeared to have sustained mortal damage, was kept afloat by her watertight bulkheads and managed to limp into harbor at St. John's, Newfoundland.

Two of the six lifeboats that left Arctic reached the Newfoundland shore safely, and another was picked up by a passing steamer, which also rescued a few survivors from improvised rafts. Among those saved was Luce, who had regained the surface after initially going down with the ship. The other three lifeboats disappeared without trace. The limited telegraph facilities of the time meant that news of Arctic's loss did not reach New York City until two weeks after the sinking. Initial public sorrow at the ship's loss quickly turned to anger at the perceived cowardice of the crew. Despite press calls for a full investigation into the disaster, none took place, and nobody was held legally responsible. Demands for the introduction of further safety measures on passenger-carrying vessels were likewise sidestepped. Luce, who was generally exonerated from blame by the public, retired from the sea; some of the surviving crew chose not to return to the U.S. The Collins Line continued its transatlantic service until further maritime losses and insolvency led to its closure in 1858.

SS Arctic was a 2,856-ton paddle steamer, one of the Collins Line, which operated a transatlantic passenger and mail steamship service during the 1850s. She was the largest of a fleet of four, built with the aid of U.S. government subsidies to challenge the transatlantic supremacy of the British-backed Cunard Line. During its four-year period of service, the ship was renowned both for its speed and for the luxury of its accommodation.

On September 27, 1854, while on passage to New York from Liverpool, Arctic collided in fog with the French steamer Vesta off the coast of Newfoundland, and sank four hours later. Arctic's lifeboat capacity was around 180, enough for less than half those on board; the boats were launched in an atmosphere of panic and disorder, and the principle of "women and children first" was ignored. From around 400 on board (250 passengers, 150 crew), 24 male passengers and 61 crew survived; all the women and children died. No one was called to account for the disaster, and no official enquiry was held. Lifeboat provision on passenger-carrying ships remained inadequate until well into the 20th century.
