The Bay Building is a six-storey building on the corner of Granville Street and Georgia Street in downtown Vancouver, British Columbia, Canada. It is a flagship store of the Hudson's Bay department store chain. The cream terra cotta building with Corinthian columns was built in 1914, 1926, and 1927. The current store was built on the site of another HBC store from 1893. The last additions were made in 1949.

The original HBC store in Vancouver was a small storefront on Cordova between Carrall and Abbott.

On October 30, 2017, HBC announced plans to sell the building, although the store would continue operating in the location as it is under a long-term lease.
