The Weyburn Security Bank Building (also referred to as the Imperial Bank of Canada Building) is located at 76 - 3rd Street in Weyburn, Saskatchewan, Canada and is a two-storey building with a glazed terracotta façade.

Backed by American interests, Weyburn Security Bank sought Minneapolis-based architectural firm of Long, Lamoureux and Long to designed the building in a Classical Revival and Chicago School that was more representative of banks in the Western US.

The building is a designated Provincial Heritage Property.

Today the building functions as an active CIBC branch.
