SS Utopia collides with HMS Anson in the Bay of Gibraltar and sinks, killing 562 of the 880 passengers on board.

SS Utopia was a transatlantic passenger steamship built in 1874 by Robert Duncan & Co of Glasgow. From 1874 to 1882 she operated on Anchor Line routes from Glasgow to New York City, from Glasgow to Bombay and from London to New York City. After 1882 she carried Italian immigrants to the United States.

On 17 March 1891 Utopia accidentally collided with the moored battleship HMS Anson in the Bay of Gibraltar. Utopia sank within 20 minutes; with a loss of 562 of 880 passengers and crew of Utopia and two rescuers from HMS Immortalité died in the accident. The sinking of Utopia was blamed on "grave error of judgement" of her captain John McKeague, who survived the accident.
