HMCS Napanee was a Flower-class corvette of the Royal Canadian Navy during the Second World War.

[3][4][5] The "corvette" designation was created by the French for classes of small warships; the Royal Navy borrowed the term for a period but discontinued its use in 1877.

[6] During the hurried preparations for war in the late 1930s, Winston Churchill reactivated the corvette class, needing a name for smaller ships used in an escort capacity, in this case based on a whaling ship design.

[11] After arriving at Halifax for deployment, Napanee was initially assigned to Sydney Force.

[12] During her time with WLEF, Napanee was part of two escort group, W-3 initially and W-2 after her second refit until the end of the war.
