If you’re new to the world of anime or just looking to dive into one of the most critically acclaimed series of all time, you’ve likely heard of Attack on Titan. Known for its breathtaking animation, gripping narrative, and intense character arcs, Attack on Titan (Shingeki no Kyojin) has carved its place as a global phenomenon. But with its unique release structure and evolving storyline, many fans find themselves wondering: How many seasons are there in Attack on Titan?

Let’s break it down in detail to help you understand not only how many seasons there are, but how each one contributes to the incredible story of humanity’s fight for survival.

A Brief Introduction to Attack on Titan

Attack on Titan is a dark fantasy anime series based on the manga of the same name by Hajime Isayama. The story is set in a post-apocalyptic world where humanity is on the brink of extinction, living behind massive walls to protect themselves from gigantic humanoid creatures known as Titans. The story follows Eren Yeager, Mikasa Ackerman, and Armin Arlert as they join the military to fight against the Titans and uncover deep-rooted secrets about their world.

Now, onto the seasons.

Season 1 (2013)

The first season of Attack on Titan premiered in 2013 and instantly made waves in the anime community. Consisting of 25 episodes, Season 1 introduces viewers to the terrifying reality of the Titans and the last bastion of humanity behind the walls. It covers the fall of Wall Maria, the formation of the Scout Regiment, and the mystery surrounding Eren’s unique ability to transform into a Titan himself.

This season sets the tone for the rest of the series — high-stakes action, emotional storytelling, and mysteries that keep audiences hooked.

Season 2 (2017)

After a long four-year gap, Season 2 aired in 2017 with a much shorter run of 12 episodes. However, what it lacked in length, it made up for in quality and revelations. Season 2 delves deeper into the identities and motivations of the Titans, including the shocking truth about some of the characters within the military ranks.

This season is pivotal, shifting the focus from mere survival to uncovering the origins of the Titans and the secrets buried within the walls.

Season 3 (2018–2019)

Attack on Titan Season 3 was released in two parts: Part 1 aired in 2018 and Part 2 in 2019, with a total of 22 episodes.

• Part 1 focuses on political intrigue within the walls, including a coup d’état to restore true leadership and expose government corruption.

• Part 2 returns to high-octane action and the battle to retake Wall Maria. It also delivers some of the most jaw-dropping reveals about the world outside the walls and the true nature of Titans.

Season 3 is often praised for its balance of action, emotion, and groundbreaking plot development. By the end of this season, the story evolves from a survival horror into a complex geopolitical drama.

Season 4 – The Final Season (2020–2023)

Now to the most asked question: “How many seasons are there in Attack on Titan?”

Technically, there are four seasons. However, the final season—Season 4—was split into multiple parts, making it feel like more than one season to many fans.

Season 4: Part 1 (2020–2021)

Season 4 begins with a major shift in perspective, exploring the world beyond the walls and introducing new characters from the nation of Marley. The story takes on a global scale, shifting from simple survival to the moral complexities of war, revenge, and cycles of hatred. This part contains 16 episodes.

Season 4: Part 2 (2022)

Continuing the explosive developments, Part 2 aired in early 2022 with 12 episodes. The narrative intensifies as Eren launches his plan to initiate the “Rumbling” — a catastrophic event that threatens to destroy the world.

Season 4: Part 3 – The Final Chapters (2023)

Rather than a traditional season format, the final chapters of Season 4 were released as two special episodes (also referred to as Part 3 Part 1 and Part 2) in 2023. These concluding chapters wrap up the massive storyline with emotional depth, high-stakes conflict, and a thought-provoking finale that left a lasting impression on fans worldwide.

Final Verdict: How Many Seasons Are There in Attack on Titan?

In simple terms, Attack on Titan consists of four main seasons:

1. Season 1 – 25 episodes

2. Season 2 – 12 episodes

3. Season 3 – 22 episodes (split into two parts)

4. Season 4 – 36 episodes + 2 specials (split into three parts)

So while there are four official seasons, the final season was expanded across several years and released in multiple segments — leading to the confusion among viewers. Altogether, the anime includes nearly 90 episodes, not counting the OVAs and special recaps.

Why the Split Season Format?

The decision to split the final season was largely due to the complexity of the story and the desire to maintain high production quality. Studio MAPPA, which took over animation duties from Wit Studio starting in Season 4, aimed to ensure the adaptation did justice to Isayama’s ambitious and emotionally layered conclusion.

Conclusion

So, how many seasons are there in Attack on Titan? Officially, four — but the structure of the final season makes it feel like much more. Each season builds on the last, transforming a simple survival tale into an epic narrative about freedom, morality, and the human condition.

Whether you’re just starting the journey or planning a rewatch, understanding the season breakdown can help you better appreciate the scale and impact of this legendary anime. One thing’s for certain: Attack on Titan has earned its place in the anime hall of fame — and now, you know exactly how its epic saga unfolds.
