Portrait of an Artist, as an Old Man is a novel by American writer Joseph Heller, published posthumously in 2000.

The story is of Eugene Pota, a prominent writer who, in his old age, is struggling for that last piece of fiction that could be his magnum opus, or at least on par with his earlier writings.

Littered throughout the novel are many of Pota's ideas and drafts of possible stories, such as the sexual biography of his wife, or of Hera's trouble with Zeus.

The title is evocatively similar to James Joyce's A Portrait of the Artist as a Young Man.

"[4] Tim Adams, writing for The Guardian, was more positive, calling it a "moderate success" and describing it as a "caustic self-parody".
