The Canada-class ships of the line were a series of four 74-gun third rates designed for the Royal Navy by William Bateley.

During this period in British naval architecture, the 74-gun third rates were divided into two distinct groupings: the 'large' and 'common' classes.

The Canada-class ships belonged to the latter grouping, carrying 18-pounder guns on their upper gun decks, as opposed to the 24-pounders of the large class.

HMS Captain, made famous for Nelson's actions at the Battle of Cape St Vincent, belonged to this class of ships.
