Frankenstein : The Modern Prometheus is an 1818 novel written by Mary Shelley. Frankenstein tells the story of Victor Frankenstein, a young scientist who creates a sapient creature in an unorthodox scientific experiment. Shelley started writing the story when she was 18, and the first edition was published anonymously in London on 1 January 1818, when she was 20. Her name first appeared in the second edition, which was published in Paris in 1821.

Since the publication of the novel, the name "Frankenstein" has often been used, erroneously, to refer to the monster, rather than to his creator.
