HMS Odin was a British Oberon-class submarine operated by the Royal Navy.

The Oberon class was a direct follow on of the Porpoise-class, with the same dimensions and external design, but updates to equipment and internal fittings, and a higher grade of steel used for fabrication of the pressure hull.

[2] Propulsion machinery consisted of 2 Admiralty Standard Range 16 VMS diesel generators, and two 3,000 shaft horsepower (2,200 kW) electric motors, each driving a 7-foot-diameter (2.1 m), 3-bladed propeller at up to 400 rpm.

[2] Eight 21-inch (530 mm) diameter torpedo tubes were fitted (six facing forward, two aft), with a total payload of 24 torpedoes.

[2] Odin was laid down by Cammell Laird on 27 April 1959, and launched on 4 November 1960.
