The Farr House is a historic house located at 106 E. Wynoka St. in Pierre, South Dakota. Built in 1904, the house was designed by architect E. J. Donahue in the Colonial Revival style. Donahue's design exhibits Georgian and Adamesque influences and features Ionic columns on the porch, two-story Ionic pilasters at the front corners, Palladian windows, and a dentillated cornice. The house's first owner, Colonel E. P. Farr, was a veteran and banker; his wife, Mary Noyes Farr, was one of the first female doctors in Pierre. Peter Norbeck later lived in the house during his term as South Dakota Governor, and Governor Carl Gunderson also lived in the house for a short time. The house is now a bed and breakfast.
