Rabbit of Caerbannog
fictional animal in the film Monty Python and the Holy Grail

The Rabbit of Caerbannog (), often referred to in popular culture as the Killer Rabbit, is a fictional character who first appeared in the 1975 comedy film Monty Python and the Holy Grail by the Monty Python comedy troupe, a parody of King Arthur's quest for the Holy Grail. The character was created by Monty Python members Graham Chapman and John Cleese, who wrote the sole scene in which it appears in the film; it is not based on any particular Arthurian lore, although there had been examples of killer rabbits in medieval literature. It makes a similar appearance in the 2004 musical Spamalot, based on the film.
The Killer Rabbit appears in a major set piece battle towards the end of Holy Grail, when Arthur and his knights reach the Cave of Caerbannog, having been warned that it is guarded by a ferocious beast. They mock the warning when they discover the beast to look like a common, harmless rabbit, but are brutally forced into retreat by the innocent-looking creature, who injures many of Arthur's knights and even kills several before being killed in return by Arthur, who uses a holy weapon, the Holy Hand Grenade of Antioch, to blow up the beast.
The "Killer Rabbit scene" is largely regarded as having achieved iconic status, and it is considered one of Monty Python's most famous gags; it has been referenced and parodied many times in popular culture, and it was important in establishing the viability of Spamalot. Despite its limited screentime, several publications have acknowledged the Rabbit of Caerbannog as one of the best and most famous fictional bunnies in film history.

Why this record matters
“Rabbit of Caerbannog” is worth following because a concise public description often conceals a longer documentary argument. Here, Rabbit, Caerbannog and fictional provides the most credible route into that argument.
Attribution, date and provenance are strongest when supported by the original work, a catalogue record and documented transmission. The source revision retrieved here is dated Jul 27, 2026.

Later fame can flatten the distinction between original context, subsequent adaptation and institutional collecting history. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
