Template:Spoiler Rikki-Tikki-Tavi is a short story in The Jungle Book (1894) by Rudyard Kipling about the adventures of a valiant young mongoose.

An English family, who have moved to a house in India, discover a young mongoose half drowned from a storm and decide to keep it as a pet. The young mongoose, called Rikki-Tikki , soon finds himself confronted by two murderous cobras, Nag and Nagaina, who had had the run of the garden while the house was unoccupied. After that first encounter with the cobras, Rikki's first true battle is with Karit, a small venomous sand snake who threatens the boy. Although Rikki is inexperienced and the snake, because of its deadly venom and small size, is an even more dangerous foe than a cobra, the mongoose defeats him.

As Nagaina's urging, Nag plans to kill the human family to get the house empty again so they can have free run of its garden again. Nag goes to the bathroom to wait to kill the "big man", and goes to sleep while waiting. Rikki grabs Nag by the head above the hood. Nag thrashes about furiously, and the noise wakes the man, who fires both barrels of a shotgun into Nag and almost hitting Rikki. Nag is thrown on the rubbish heap, where Nagaina vows vengeance.

Rikki, well aware of the threat, enlists a tailor bird to distract Nagaina while he searches for her eggs. However, while he finds and destroys most of the brood, Nagaina arrives and threatens to kill the family's son with her poisonous bite, as the family is now in the garden. Alerted to the crisis, Rikki races to his family with the last egg. Once there, Rikki claims he killed Nag himself while showing the egg to distract Nagaina long enough for the man to pull the boy to safety. Nagaina snatches the egg and flees to her hole while Rikki pursues her inside. The underground fight is not described, but after a agonizingly long wait, Rikki comes out of the hole in triumph having killed Nagaina. With that victory, Rikki spends the rest of his days defending the family garden where no snake would dare enter.

The word nag is Hindi for "cobra".

The story is a favorite of Kipling fans and is notable for its frightening and serious tone. Some epic features (heightened prosaic style; songs to the hero) add to the standard typology of hero defeating villain. It has often been anthologised and has also been published more than once as a short book in its own right.

A short animated version first aired on CBS January 9, 1975 was directed by Chuck Jones and narrated by Orson Welles. Family Home Entertainment has released this version of Rikki-Tikki-Tavi on both VHS and DVD formats. The DVD is paired with another of Jones' cartoons, Yankee Doodle Cricket.
