The Annapolis class destroyer escort was a class of ships that saw service with the Royal Canadian Navy and Canadian Forces from the 1960s-1990s.

The RCN had intended to place a six ship order under the Mackenzie-class of destroyer escorts, however the last two vessels were built to the St. Laurent-class DDH design and were classed under the new Annapolis-class designation. Both ships spent the majority of their career split between Canada's Pacific and Atlantic coasts with the Annapolis being at Esquimalt and Nipigon at Halifax.

The two Annapolis-class destroyers were built late enough to incorporate the helicopter hangar retrofitted to the St. Laurent-class. HMCS Nipigon underwent a DELEX (DEstroyer Life EXtension) refit in 1982 to upgrade combat, radar and weapons systems and HMCS Annapolis followed in 1984. Nipigon remained in the fleet until 1998 as a trials ship for the ETASS Mod 5 towed sonar system which was a precursor to the CANTASS (Canadian Towed Array Sonar System) that is currently fitted on the Halifax-class of frigates. Nipigon was the last steam-powered warship to serve in the Canadian Forces.
