The Henry Weinhard Brewery complex, also the Cellar Building and Brewhouse and Henry Weinhard's City Brewery, is a former brewery in Portland, Oregon. Since 2000, it has been listed on the National Register of Historic Places. In that same year, construction began to reuse the property as a multi-block, mixed-use development known as the Brewery Blocks.

Henry Weinhard was a German-American brewer in Portland, Oregon. After immigrating to the United States in 1851, he lived in Philadelphia, Cincinnati, St. Louis, and Sacramento before settling in the Portland area. Weinhard worked for others in the beer business before buying his own brewery and founded Henry Weinhard's and built its brewery complex in downtown Portland.
