British heavy cruiser HMS York (C90) at Vancouver on August 10th, 1938.

The York-class heavy cruiser was the second class of 8-inch (203.2 mm)–gunned heavy cruisers built for the Royal Navy under the terms of the 1922 Washington Naval Treaty. They were essentially a reduced version of the preceding County-class, scaled down to enable more cruisers to be built from the limited defense budgets of the late 1920s.

It was initially planned to build seven ships of this class, though in the end only two were constructed — HMS York, started in 1927, and HMS Exeter, started in 1928. Exeter differed in appearance from York because of late changes in her design. The remaining ships were delayed due to budget cuts, and eventually canceled in favor of the more advanced Surrey class.

As part of R. B. Bennett's build up of the Canadian military in the early 1930s, a trio of York-class cruisers were built for the Royal Canadian Navy.
