The Campbell Baking Company is a historic building located in Waterloo, Iowa, United States.

Built in 1927, the single-story, yellow brick structure is basically a utilitarian building with Spanish Revival decorative elements on its primary and secondary façades.

The original building was designed by the Toledo, Ohio architectural firm of Mills, Rhines, Bellman & Nordhoff, and built by the John G. Miller Construction Company.

The building represents the consolidation of the bakery industry in the early 20th century from neighborhood retail bakers to local wholesalers to national industrial wholesale bakery companies.
