There’s not much to tell about Attack on Titan that you already don’t know. Probably one of the biggest anime franchises in the last decade, Attack on Titan’s popularity skyrocketed for its incredible world-building and the complexities surrounding it.
But what contributed to its global fame is the diverse cast of characters, especially Eren Yeager, who seems to have an affinity towards his antagonistic side while being the main protagonist of the story.
His actions in the latter half of the story show that. However, from Eren’s perspective, his actions are justifiable to a certain extent. After getting cornered by the entire world, Eren takes on the burden to protect his people. This burden soon takes a toll on his teenage boy when he starts looking older than he is.
In Attack on Titan Season 4, Eren might look like someone around his early to mid-20s, but that can’t be further from the truth.
Eren Yeager is 19 years old in the Final Season of Attack on Titan. And why Eren looks older for his age lies in the fact that he is saddled with the power to protect his people, the Eldians, while the entire world is ready to butcher them without any hesitation.
Enough blabbering; let’s dive right into the guide, where I’ll take you through Eren’s age throughout every anime season.
NOTE: If you don’t have time to read the entire guide, just read the following section; it has every bit of information regarding Eren’s age you will ever need.
How Old is Eren Yeager?
Eren Yeager is currently 19 years old in the year 854. It is the year when The Rumbling takes place.

In the year 845, when Eren was 10 years old, the Colossal Titan breached Wall Maria. During the Titan invasion, Eren lost his mother to a Titan.
In 847, Eren was 12 years old when he joined the 104th Training Corps to become stronger and join the Survey Corps at completion.

In 851, a 16-year-old Eren, alongside the Survey Corps member, finally embarks on a journey outside the walls and reaches the sea, something he has only dreamt of.
In 854, a 19-year-old Eren launched a surprise attack on the enemy homeland, Marley. The battle triggered a counterattack from Marley, which led to Eren using the Founding Titan’s power to unleash the Wall Titans upon the entire world beyond the walls.

How Old is Eren Yeager in Season 1?

In Attack on Titan Season 1, Eren Yeager was 10 years old. He admired the Survey Corps, but his mother was strictly against the idea of her son getting involved anywhere near the life-threatening job of a Survey Corps member.
At the mere age of 10, Eren saw his mother getting eaten by a titan. He promises to eradicate every single titan from the face of the earth.
Eren’s Age: 12 years old
At 12, Eren, with Mikasa and Armin, enlisted into the 104th Training Corps for a 3-year training period. They joined not only to become stronger and protect themselves but also to avenge the loved ones they lost during the invasion of the Titans.
Especially Eren, whose resolve to exterminate the Titans fueled his spirit. Hundreds of other aspiring candidates enlisted alongside them. Among them was the main cast of supporting characters, who would soon become friends or enemies.
Eren’s Age: 15 years old
After three years of training, Eren ranked among the top ten trainees and joined the Survey Corps. Soon, Wall Rose gets breached by the same Colossal Titan who breached Wall Maria, resulting in Eren’s mother’s demise.
This time, Eren witnesses many of his comrades’ deaths but soon finds himself in a dilemma when he transforms into a titan and fights off the invading ones, ending up as the target of the Survey Corps instead.
At the end of Season 1, 15-year-old Eren discovers that Annie Leonheart is one of the infiltrators who killed several humans.

In Attack on Titan Season 2, Eren is 15 years old when Wall Rose gets breached. He was 15 in the entire season. The second season reveals one of the most important secrets for Eren. He discovers that many whom he thought to be allies are his enemies.
The ones responsible for the invasion of Wall Maria resulting in his mother’s demise were Bertholdt (Colossal Titan) and Reiner (Armored Titan). Eren gets kidnapped by his former allies, but the Survey Corps get him back, costing more than half their numbers.
During the confrontation, Eren discovers that he can control Titans, which is the reason behind his kidnapping. Season 2 ends with Eren more determined than ever to hone his newfound skills and capture Reiner and Co.

He got kidnapped once again and almost got eaten by Historia to inherit his titan powers. He also unravels how he became the titan – by eating his father.
Besides that, in AOT S3, the history of the Reiss family is revealed. The Survey Corps fights the Beast Titan, and Levi saves Armin’s life over Erwin’s. After these incidents, Eren, Levi, Mikasa, and Hange go to Eren’s house (basement) to find out what Grisha’s keys lead to.
At the end of S3 Part 2, 16-year-old Eren ventures outside the wall along with Survey Corps and reaches the sea only to realize that across the vast blue are the enemies that want to wipe them out. Meanwhile, Eren’s smile disappears from the inherited memories of the future he has been experiencing.
How Old is Eren Yeager in Season 4?
Eren’s Age: 19 years old
Attack on Titan Season 4 starts four years after the failed mission of reclaiming the Founding Titan. Eren is 19 years old in the beginning and will remain 19 till the end of the final season (Season 4).
In this final season, we get introduced to the new characters from Marley. Eren and the Survey Corps ambushed Marley before they could wage war on Paladis. Soon, Marley attacks the island, and both sides suffer casualties.
In Season 4 Part 2, we see Eren Yeager unleashing all the Wall Titans on the world beyond the walls to not only protect his people but also achieve freedom from the cage he has been living inside since childhood.
In Season 4 Part 3 – divided into two parts, we see the Survey Corps and Marley’s Warrior Unit join hands to stop Eren from destroying the entire world and put an end to The Rumbling.
From his childhood till his teenage days, Eren’s life was painful, heartbreaking, filled with bloodbaths, and a curse that unfortunately ended with his death. At 10, he saw his mother’s death; growing up, he saw his friends and comrades getting eaten or killed by the Titans, and at 19, Eren took it upon himself to protect his people by becoming like those whom he loathed since the beginning.
Eren’s life stopped at 19, but he has experienced much more than anyone; he has suffered more than anyone; now, let’s hope he gets to rest in peace at a place where freedom ensues.
