HMS Weymouth was a Town-class light cruiser built for the Royal Navy during the 1910s.

The ship reached 25.95 knots (48.06 km/h; 29.86 mph) during her sea trials from 23,380 shp (17,430 kW).

[6] One problem with the armour of the Weymouths which was shared with the other Town-class ships was the sizable gap between the bottom of the gun shields and the deck, which allowed shell splinters to pass through the gap, which resulted in leg injuries to the ships' gun crews.

[7] The ship was laid down on 19 January 1910 by Armstrong Whitworth at their Elswick shipyard and launched on 18 November.

In August 1914, Weymouth was detached to sail into the Indian Ocean to hunt for the German light cruiser SMS Emden, which was raiding Allied shipping in the area.

In 1916 she returned to home waters and was assigned to the 6th Light Cruiser Squadron of the Grand Fleet.
