Hop-Frog is a short story by American writer Edgar Allan Poe, first published in 1849. The title character is a dwarf taken from his homeland who becomes the jester of a king particularly fond of practical jokes.
Taking revenge on the king and his cabinet for striking his friend and fellow dwarf Trippetta, he dresses them as orangutans for a masquerade. In front of the king's guests, Hop-Frog murders them all by setting their costumes on fire before escaping with Trippetta.
It has been suggested that Poe wrote the story as a form of literary revenge against a woman named Elizabeth F. Ellet and several others.
