The world's oldest surviving clipper ship, the City of Adelaide is launched by William Pile, Hay and Co. in Sunderland, England, for transporting passengers and goods between Britain and Australia.

City of Adelaide is a clipper ship, built in Sunderland, England, and launched on 7 May 1864. It was built by Pile, Hay and Co. to transport passengers and goods between Britain and Australia. Between 1864 and 1887 she made 23 annual return voyages from London and Plymouth to Adelaide, South Australia and played an important part in the immigration of Australia. On the return voyages she carried passengers, wool, and copper from Adelaide and Port Augusta to London. From 1869 to 1885 she was part of Harrold Brothers' "Adelaide Line" of clippers.

After 1887, the ship carried coal around the British coast, and timber across the Atlantic. In 1893, she became a floating hospital in Southampton, and in 1923 was purchased by the Royal Navy. The ship was commissioned in the Royal Navy as HMS Carrick (to avoid confusion with the newly commissioned HMAS Adelaide), and based in Scotland as a training ship. In 1948, she was decommissioned and donated to the Royal Naval Volunteer Reserve Club, and towed into central Glasgow for use as the club's headquarters and remained on the River Clyde until 1989 when she was damaged by flooding. In order to safeguard the vessel, she was protected as a listed building, but in 1991 she sank at her mooring. Carrick was recovered by the Scottish Maritime Museum the following year, and moved to a private slipway adjacent to the museum's site in Irvine.

Restoration work began, but funding ceased in 1999, and from 2000 the future of the ship was in doubt. After being served with an eviction notice by the owners of the slipway, the Scottish Maritime Museum was forced to seek the deconstruction of the ship on more than one occasion, while rescue proposals were developed by groups based in Sunderland and South Australia. At a conference convened by the Duke of Edinburgh in 2001, the decision was made to revert the ship's name to City of Adelaide. In 2010, the Scottish Government decided that the ship would be moved to Adelaide, to be preserved as a museum ship, and the duke formally renamed her at a ceremony in 2013. In September 2013, the ship was moved by barge from Scotland to the Netherlands to prepare for transport to Australia. In late November 2013, loaded on the deck of a cargo ship, City of Adelaide departed Europe bound for Port Adelaide, where she arrived on 3 February 2014.

A clipper was a type of mid-19th-century merchant sailing vessel, designed for speed. Clippers were generally narrow for their length, small by later 19th century standards, could carry limited bulk freight, and had a large total sail area. "Clipper" does not refer to a specific sailplan; clippers may be schooners, brigs, brigantines, etc., as well as full-rigged ships. Clippers were mostly constructed in British and American shipyards, though France, Brazil, the Netherlands and other nations also produced some. Clippers sailed all over the world, primarily on the trade routes between the United Kingdom and China, in transatlantic trade, and on the New York-to-San Francisco route around Cape Horn during the California Gold Rush. Dutch clippers were built beginning in the 1850s for the tea trade and passenger service to Java.The boom years of the clipper era began in 1843 in response to a growing demand for faster delivery of tea from China. This continued under the stimulating influence of the discovery of gold in California and Australia in 1848 and 1851, and ended with the opening of the Suez Canal in 1869.
