HMCS Terra Nova (DDE 259) was a Restigouche-class destroyer that served in the Royal Canadian Navy and later the Canadian Forces from 1959 until 1997. After her final refit, she was a guided missile destroyer.

She was the sixth ship of her class and the first Canadian war ship to bear the name HMCS Terra Nova. The ship's badge honours the Terra Nova River in Newfoundland as well as an earlier civilian ship, Terra Nova, which gained fame during a scientific exploration voyage to Antarctica. They are represented as a river and the Antarctic (symbolized by a penguin) on the ship's badge.

Based on the preceding St. Laurent-class design, the Restigouches had the same hull and propulsion, but different weaponry. Initially the St. Laurent class had been planned to be 14 ships. However the order was halved, and the following seven were redesigned to take into improvements made on the St. Laurents. As time passed, their design diverged further from that of the St. Laurents.

The ships had a displacement of 2,000 tonnes (2,000 long tons), 2,500 t (2,500 long tons) at deep load. They were designed to be 112 metres (366 ft) long with a beam of 13 metres (42 ft) and a draught of 4.01 metres (13 ft 2 in). The Restigouches had a complement of 214.

The Restigouches were by powered by two English Electric geared steam turbines, each driving a propellor shaft, using steam provided by two Babcock & Wilcox boilers. They generated 22,000 kilowatts (30,000 shp) giving the vessels a maximum speed of 28 knots (52 km/h; 32 mph).
