National Lampoon's Doon is a parody of Frank Herbert's 1965 science fiction novel Dune, written by Ellis Weiner and published in 1984 by Pocket Books for National Lampoon. It was reprinted by Grafton Books () in 1985. In 1988 William F. Touponce called the book "something of a tribute to Herbert's success on college campuses", noting that "the only other book to have been so honored is Tolkien's The Lord of the Rings," which was parodied by The Harvard Lampoon in 1969. Dune is set on the dangerous, sandworm-ridden desert planet Arrakis, sole source of the spice melange, the most valuable substance in the universe. The parody follows a similar storyline, wherein rival restaurant-owning families battle for control of Arruckus, which is overrun by giant pretzels and the source of valuable beer.

Found naturally on Arruckus as a result of natural processes and nowhere else, it is the engine on which commerce runs; the Schlepping Guild, who has a monopoly on space travel in the Imperium, will not run without it. Who controls the beer controls commerce. But soon after arriving on Doon, with his heir and son Pall and his concubine the Lady Jazzica, an adept of the galaxy-spanning sisterhood of chefs and event planners known as the Boni Maroni, Duke Lotto and House Agamemnides fall victim to a scheme originated by Baron Vladimir Hardchargin and implemented by the Duke's own accountant Oyeah, who, without the Duke's knowledge, kept a secret second ledger. When the Emperor called for an audit of the fief, the duplicate ledger made it appear as though House
