HMS Isis was an Eclipse-class protected cruiser built for the Royal Navy in the mid-1890s.

Using normal draught, the boilers were intended to provide the engines with enough steam to generate 8,000 indicated horsepower (6,000 kW) and to reach a speed of 18.5 knots (34.3 km/h; 21.3 mph); using forced draft, the equivalent figures were 9,600 indicated horsepower (7,200 kW) and a speed of 19.5 knots (36.1 km/h; 22.4 mph).

In the wake of a violent riot by Cretan Turks against British soldiers, sailors, and Christian civilians in Candia on 6 September 1898, Isis anchored in the harbor and men convicted of murdering British subjects during the riot were held aboard her while awaiting trial and execution.

[16] In May 1902, she was briefly tender to HMS Britannia, cadet training ship at Dartmouth.

[20] On 22 April 1914, she collided with the British cargo ship Carbineer in the English Channel, sinking Carbineer 1.5 nautical miles (2.8 km) south-southeast of the Owers Lightship; Isis rescued Carbineer′s crew.

[21] In August 1914 with the outbreak of war, Isis was brought out of the reserve and attached to the 11th Cruiser Squadron based on Queenstown (now Cobh), Ireland.
