RMS Titanic was a British passenger liner that sank in the North Atlantic Ocean in the early morning of 15 April 1912, after colliding with an iceberg during her maiden voyage from Southampton to New York City. Of the 2,224 passengers and crew aboard, more than 1,500 died in the sinking, making it one of the deadliest commercial peacetime maritime disasters in modern history. The largest ship afloat at the time it entered service, the RMS Titanic was the second of three Olympic class ocean liners operated by the White Star Line, and was built by the Harland and Wolff shipyard in Belfast.

The sheer size of Titanic and her sister ships posed a major engineering challenge as no shipbuilder had ever before attempted to construct vessels this size. The Titanic was constructed on Queen's Island, now known as the Titanic Quarter, in Belfast Harbour.
