The Nãointendo Co. Ltd. (株式会社 わ か ら な い, Naointendō Kabushikigaisha?) Is a Japanese manufacturer of electronic games. She is one of the largest companies in the industry and also one of the great symbols of the world due to her sales success and extensive work in creating charismatic characters with the public.

Commonly, it is assumed that the name "Nãointendo" means "Do not leave luck to heaven" in Portuguese, but there is no historical record to validate this assumption.
