Queen Anne Cottage and Coach Barn is a Victorian style pair of buildings at Baldwin Lake, on the grounds of the Los Angeles County Arboretum and Botanic Garden, located in Arcadia and the San Gabriel Valley of southern California.

They are a California Historical Landmark, and were placed on the National Register of Historic Places for their significance as examples of Queen Anne Style architecture and for the associated, largely intact Victorian landscape design gardens.

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.

[4] In 1993 the "X"-pattern fencing around the Queen Anne Cottage was refurbished and repaired as part of an Eagle Scout project by Erik Wanson, a member of Boy Scout Troop 351 in San Marino, California.
