The B.J. Palmer House, also known as the Palmer Family Residence, is a historic building located on the Brady Street Hill in Davenport, Iowa, United States. It is on the campus of Palmer College of Chiropractic and has been listed on the National Register of Historic Places since 1984. The college offers tours of the first floor of the mansion. B.J. Palmer Bartlett Joshua Palmer (1882–1961) was the son of Daniel David Palmer, who established the practice of chiropractic. B.J. Palmer convinced his father to establish a school of chiropractic in Davenport. In the first decade of the 20th century, B.J. Palmer purchased the mansions built by J.C. Duncan, W.D. Petersen and Thomas Barron on the top of Brady Street for the school. He served the college as its president and is credited with the development of chiropractic.

It was the second commercial radio station in the United States and the first west of the Mississippi River.

The Petersen family redecorated the house in 1905. They had the parquet floors, painted plaster moldings and Italian marble fireplaces installed in the house. Palmer acquired the property in 1912 for $25,000. In 1921-1922 he had the enclosed porch built around the structure that created a room for entertaining. In most cases this would be considered a significant alteration of the original building, but because it reflects Palmer's peculiar personality and his disassociation from the traditional tastes of Davenport's elite, it is significant in its own right. The porch is an odd assortment of institutional form with residential features such as the beveled glass. WOC radio had its first studio on the porch. The home contains an Aeolian player pipe organ that was purchased by the Palmers for $75,000. B.J. Palmer's favorite room in the house was called the
