Queen Anne Cottage and Coach Barn is a National Register of Historic Places structure (site #80000804) on the grounds of the Los Angeles County Arboretum and Botanic Garden in Arcadia, California. It was placed on the Register in 1980 for its significance as an example of Queen Anne Style architecture and for the associated, largely intact Victorian landscape.
The Cottage was constructed in 1885-1886 for Elias Jackson "Lucky" Baldwin and his fourth wife, Lillie Bennett, the daughter of the Cottage's architect Albert A. Bennett. Upon E.J.'s death in 1909, his daughter closed the Cottage and disposed of all furnishings. Some of the architectural elements of the Cottage, such as the stained glass windows, black walnut doors, and marble fireplace mantels were stored in the coach barn. The stored items were reinstalled in the Cottage during the 1951-1953 restoration.
