The Baum Building was a historic building in Oklahoma City, Oklahoma. In 1909, Moses J. Baum, a Mississippi-born merchant who specialised in women's garments, leased the land at the northeast corner of Grand and Robinson and built a five-story commercial building on the site. The building was modeled after the Doge's Palace in Venice, Italy. The building was completed in 1910, with the Baum company moving in on May 5, 1910. The building was designed by Layton and Smith, and cost $140,000 to build.
