HMS Rosario (J219) was a steam turbine-powered Algerine-class minesweeper during the Second World War.

The engines produced a total of 2,000 indicated horsepower (1,500 kW) and gave a maximum speed of 16.5 knots (30.6 km/h; 19.0 mph).

They carried a maximum of 660 long tons (671 t) of fuel oil that gave them a range of 5,000 nautical miles (9,300 km; 5,800 mi) at 10 knots (19 km/h; 12 mph).

She made multiple port calls to Tunis, Port Said, Massawa, Colombo, Djakarta, Fremantle, Melbourne, Sydney, Brisbane, Cairns, Gladstone, Townsville, Darwin, Singapore, Cochin, Diego Suarez, Cape town, Abidjan and Tenerife.

The ship had to return via South Africa due to the ongoing War of Attrition between Egypt and Israel.
