In Japan, long-running anime like Naruto air weekly year-round, not in seasonal blocks (spring, fall, etc.). The “season” division was created by Western distributors (Viz Media) and streaming services for easier packaging and viewing. So, asking “how many seasons” is really asking about the Western release format.

Often listed as 9 seasons . This occurs because broadcasters split larger blocks of episodes into smaller, story-arc-based segments.

Additionally, there are several spin-off series, movies, and OVAs (original video animations) that expand on the Naruto universe.
