Rainsford Historic District, Victorian residential district in Cheyenne, United States.

Rainsford Historic District is a residential area east of downtown Cheyenne, Wyoming, comprising Victorian houses built largely in the late 19th century. Many were designed by George D. Rainsford, a New York architect who moved to Cheyenne in the late 1870s. The district includes the former Wyoming Governor's Mansion and the William Sturgis House, both individually listed on the National Register of Historic Places.

George D. Rainsford, a New York architect, reached Cheyenne in the late 1870s, bred horses and designed houses for his cattle-ranching friends. The district was listed on the National Register of Historic Places on November 6, 1984. It contains the former Wyoming Governor's Mansion and the William Sturgis House, both separately listed.

The district's nickname, Cattle Baron Row, comes from the cattle barons who built homes here. Its houses show Stick, Eastlake, Greek Revival, Romanesque Revival and Shingle styles, and George D. Rainsford, a New York architect turned horse breeder, designed many of them as favours for ranching friends.

Walking is the best way to experience the street layout and the architecture of the homes. The terrain is flat and accessible, with a clear layout that makes navigation straightforward.

George D. Rainsford practiced architecture as a hobby and as a favor to his cattle-ranching friends, not as a profession. He had come to Cheyenne in the late 1870s and built a reputation for the quality of his horse stock, and his ranch, Diamond Ranch, is itself listed on the National Register of Historic Places.
