The Riddle House is a historic house located in Palm Beach County, Florida. It is best known for the rumors that it is a haunted house.

Built in 1905, the Riddle House was originally located in West Palm Beach. It was initially used as a funeral parlor and was known as the ?Gatekeeper?s Cottage?. Later on, it became the residence of Karl Riddle around the 1920s. Local tradition says that a death of a man named ?Buck? took place in the house. Other tales tell of a different name (Joseph), but both were alleged to be former employees of the funeral home and cemetery. The causes of death vary, though, one from a fatal argument and the other from suicide.
