The Spellman Granite Works is a historic industrial building at 615 Phillips Boulevard in Sauk City, Wisconsin.

While it was originally built elsewhere in Sauk City for the Kahn Foundry and Wagon Company, brothers Bill, Harry, and John Spellman purchased it in 1915 and moved it to its current location two years later.

The Spellman brothers produced granite monuments and memorials, particularly tombstones and other burial markers.

They also played a role in Sauk City's civic life by donating statues for local veterans' memorials and cornerstones for new public buildings.
