The Carson Mansion is a large Victorian house located in Old Town, Eureka, California, and is "considered the most grand Victorian home in America." It is one of the most written about and photographed Victorian houses in California and possibly also in the United States.

Images of the house are prevalent in website designs and video animations as well as on posters, paintings, and book covers. This popularity also has led to replicas being created in amusement parks, including the clock tower on the train station at Disneyland. The home also serves as a model for haunted house artwork and design.
