Nagaina is a wicked female black cobra and is one the main antagonists of Rudyard Kipling's story, Rikki-Tikki-Tavi, and the 1975 Chuck Jones animated short based off it.
In the short, she was voiced by the late June Foray.
Nagaina was the wife of Nag and an enemy of Rikki-Tikki-Tavi the mongoose. Nag and Nagaina lived in a garden alone until a British family moved in an built a bungalow. They despised the family for taking over their territory and sought to kill them. They were often at odds with Rikki-Tikki, the family's pet.
After Nag was killed by Rikki-Tikki, Nagaina swore revenge on the humans, believing the father and his gun were the cause of her husband's death. While the family was having tea outside, Nagaina approached them, threatening to strike if they make any movement. Meanwhile, while a tailor bird distracted Nagaina, Rikki-Tikki enters the cobras' nest and crushes their eggs except for one. Before Nagaina could bite the son Teddy, Rikki-Tikki showed up with the last egg, threatening to smash it if she attacked the family. Nagaina stole her egg back and retreated into her nest, but Rikki-Tikki chased her down and killed her there.
