Belvedere House is a historic townhouse on Great Denmark Street in Dublin, Ireland. It was built as a townhouse in 1775 for George Rochfort, 2nd Earl of Belvedere at a cost of £24,000. In 1841 it became a Jesuit college. It is allegedly haunted by the ghost of Rochfort's mother, Mary Molesworth, 1st Lady of Belvedere, who died there.
