The Karsner-Carroll House (also known as the Oscar Kennedy House) is a historic residence in Florence, Alabama. The lot on which the house sits was purchased in 1818 by James Gadsden; the lot to the west was purchased by his commanding officer in the War of 1812, Andrew Jackson. The house was built sometime before 1830 by B. F. Karsner. In 1902 it was purchased by Dr. George W. Carroll, whose daughter Bertha later lived in the house with her husband Oscar Y. Kennedy. The house was listed on the National Register of Historic Places in 1970.
