HMCS Rainbow was an Apollo-class protected cruiser built for Great Britain's Royal Navy as HMS Rainbow entering service in 1892. Rainbow saw time in Asian waters before being placed in reserve in 1909. In 1910 the cruiser was transferred to the Royal Canadian Navy for service on the west coast. During the First World War, Rainbow was the only major Commonwealth warship on the western coast of North America at the outbreak of war. Due to age, the cruiser was taken out of service in 1917 and sold for scrap in 1920 and broken up.

The Apollo-class cruisers were enlarged versions of the preceding Marathon class. Rainbow displaced 3,600 long tons (3,700 t), which made the ship heavier than some of her sister ships. This was due to being among the ten vessels in the class sheathed in wood and copper for tropical service. This added 200 long tons (200 t) to their displacement. The Apollo-class cruisers were 300 feet (91 m) long between perpendiculars and 314 feet (96 m) overall. Sheathed vessels had a beam of 43 feet 8 inches (13.31 m) and a draught of 18 feet 6 inches (5.64 m). The cruisers were propelled by a two shaft, two-cylinder triple expansion engine powered by steam from three double-ended and two single-ended boilers creating 7,000 indicated horsepower (5,200 kW) at natural draught and 9,000 indicated horsepower (6,700 kW) at forced draught. This gave the cruisers a maximum speed of 18.5 knots (34.3 km/h; 21.3 mph) at natural draught and 19.75 knots (36.58 km/h; 22.73 mph) at forced draught. The Apollo class carried 535 long tons (544 t) of coal for fuel. With full bunkers of coal, the cruisers had a range of 8,000 nautical miles (15,000 km; 9,200 mi) at 10 knots (19 km/h; 12 mph).
