The Author of Beltraffio is a short story by Henry James, first published in the English Illustrated Magazine in 1884. This macabre account of desperate family infighting eventually leads to a tragic conclusion. Although the father in the story is a novelist, the tale concentrates far more on his family relationships than on his special concerns as a writer, though some of those concerns affect the outcome.

Henry James, OM, son of theologian Henry James Sr., brother of the philosopher and psychologist William James and diarist Alice James, was an American-born author, one of the founders and leaders of a school of realism in fiction. He spent much of his life in England and became a British subject shortly before his death. He is primarily known for a series of major novels in which he portrayed the encounter of America with Europe. His plots centered on personal relationships, the proper exercise of power in such relationships, and other moral questions. His method of writing from the point of view of a character within a tale allowed him to explore the phenomena of consciousness and perception, and his style in later works has been compared to impressionist painting.
