HMS Felixstowe was a Bangor-class minesweepers built for the Royal Navy during the Second World War.

The Bangor class was designed as a small minesweeper that could be easily built in large numbers by civilian shipyards; as steam turbines were difficult to manufacture, the ships were designed to accept a wide variety of engines.

The engines produced a total of 2,400 shaft horsepower (1,800 kW) and gave a maximum speed of 16 knots (30 km/h; 18 mph).

The ship carried a maximum of 160 long tons (163 t) of fuel oil that gave her a range of 2,800 nautical miles (5,200 km; 3,200 mi) at 10 knots (19 km/h; 12 mph).

She struck a mine on 18 December 1943 and sank east of Capo Ferro, Sardinia, Italy.
