HMCS Victoria is a long-range hunter-killer (SSK) submarine of the Royal Canadian Navy, the lead ship of her class. She is named after the city of Victoria, British Columbia. She was purchased from the Royal Navy, and is the former HMS Unseen (S41). The class was also renamed from the Upholder class.

As built the Upholder/Victoria class was designed as a replacement for the Oberon class for use as hunter-killer and training subs. The submarines, which have a single-skinned, teardrop-shaped hull, displace 2,220 long tons (2,260 t) surfaced and 2,455 long tons (2,494 t) submerged. They are 230 feet 7 inches (70.3 m) long overall with a beam of 25 feet 0 inches (7.6 m) and a draught of 17 feet 8 inches (5.4 m).

The submarines are powered by a one shaft diesel-electric system. They are equipped with two Paxman Valenta 1600 RPS SZ diesel engines each driving a 1.4-megawatt (1,900 hp) GEC electric alternator with two 120-cell chloride batteries. The batteries have a 90-hour endurance at 3 knots (5.6 km/h; 3.5 mph). The ship is propelled by a 4.028-megawatt (5,402 hp) GEC dual armature electric motor turning a seven-blade fixed pitch propeller. They have a 200-long-ton (200 t) diesel capacity. This gives the subs a maximum speed of 12 knots (22 km/h; 14 mph) on the surface and 20 knots (37 km/h; 23 mph) submerged. They have a range of 8,000 nautical miles (15,000 km; 9,200 mi) at 8 knots (15 km/h; 9.2 mph) and 10,000 nautical miles (19,000 km; 12,000 mi) at snorting depth. The class has a reported dive depth of over 650 feet (200 m).
