Why didn't Jiraiya tell Naruto who his parents are?

Answer 1

Naruto wasn't told who his father was because if word got out he was the the Fourth Hokages son he would have assassins from other hidden villages trying to kill him (Ex. Iwagakure) and others trying to abduct him and use him for his power and potential (Ex. Danzo and Kumogakure)

Answer 2

Minato himself. He seal himself in Naruto's stomach so incase in future if the seal is to be broken. He would appear in Naruto subconciousness. When the seal was about to break when Naruto was fighting Pein, Minato appear in Naruto's subconciousness and tell him everything.

Answer 3

They kept this secret from him to protect him from other villages and lands that were looking for the fox. They all did it in protection. It was also something the 4th hokage wanted. The 4th hokage's life was kept secret from a lot of people.

Answer 4

Because he couldn't because he promised Minato not to tell Naruto he's parents heritage, just before he sacrificed him self

Answer 5

I think tsunade will tell him. Or iruka will as iruka has agued about not letting him know in the past many times.
