The tailed beasts (尾獣, bijū) are the nine titanic behemoths within the Naruto series. They are differentiated by the number of tails they have, ranging from one to nine. The tailed beasts are living forms of chakra, sometimes referred to as "Chakra Monsters" (チャクラのバケモノ, Chakura no Bakemono), giving them immense reserves of especially strong chakra that far outmatches most shinobi. The tailed beasts' chakra is coloured red.
They also have the ability to communicate telepathically with each other and their jinchūriki, and possess several levels of consciousness. There is the initial level where the beast may appear in a habitat of sorts seemingly imprisoned in some way by whatever fūinjutsu that sealed them. The second level is where all the tailed beasts can convene, free of any restrictions and communicate with one another. The jinchūriki are also able to enter there, but in order to do so, they must be completely linked with their tailed beasts.

Long ago before the founding of the hidden villages, during an era of endless wars between mankind, there existed the Shinju, a tree that was revered as a deity which bore a fruit once every millennia. Although it was forbidden to consume the Shinju's fruit, it was eaten by Princess Kaguya Ōtsutsuki, who used the power it granted her to end the wars plaguing the lands. Some time after this, Kaguya gave birth to two sons named Hagoromo and Hamura. They both inherited this powerful chakra and were able to manipulate it. Enraged by the fact her children inherited her powers, Kaguya merged with the Shinju into a monstrous entity of what many christened as the "Ten-Tails". The Ten-Tails rampaged throughout the lands, until Hagoromo and Hamura managed to defeat the beast by having Hagoromo become its jinchūriki.
Inspired by his younger son, Asura Ōtsutsuki, Hagoromo separated the Ten-Tails' chakra within his body and used his Creation of All Things ability to divide it into nine pieces, creating the tailed beasts and giving each a name. Some time after their creation, the young tailed beasts were told that they were all still linked to one another despite being separate entities. Hagoromo also told them that they would eventually become one again, yet not as they originally were, and that one shall appear at that time to show them what true power is. Some time later, Hagoromo sealed the Demonic Statue of the Outer Path within the moon. Despite their close relation to one another, there is a significant amount of friction between the tailed beasts that caused them to part ways. One such cause was due to Kurama's belief that their strength was determined by the number of their tails.
Over the centuries, countless humans failed to regard the tailed beasts as sapient individuals, treating them with great disdain and fear. Because of their immense power, they sought the tailed beasts out as tools to be controlled, a sentiment they detest. By the time of the formation of the shinobi villages, after his victory against Madara Uchiha in the Valley of the End, Hashirama Senju, the First Hokage, used his Wood Release techniques to capture several of the tailed beasts and allow the other shinobi villages to purchase them in exchange for signing peace treaties with each other, in order to stabilise the balance of power between them.
Madara, later revealed to have survived the altercation, had obtained Hashirama's DNA — his true purpose for the encounter. Integrating Hashirama's DNA into his wounds, Madara awakened the Rinnegan shortly before the end of his natural lifespan. With it, he was able to summon the Ten-Tails' husk from the moon. However, despite using artificial means to extend his life, Madara was unable to carry out his plan to revive the Ten-Tails. As such, he passed on this task to a young Obito Uchiha who had come to share his view on the world after Rin Nohara's death.
With the help of Akatsuki, by the time of the Fourth Shinobi World War, seven of the nine tailed beasts had been sealed into the statue. Irked by the slow progress of the plan, assuming the identity of Tobi to oversee the matters and converting reincarnated hosts into his personalised Six Paths of Pain, Obito accompanied by the statue entered the battlefield to obtain the Benihisago and Kohaku no Jōhei which contained the Gold and Silver Brothers. Despite not having sealed the last remaining two tailed beasts entirely — only possessing portions of their power, Obito decided to begin the plan as the Demonic Statue of the Outer Path undergoes a painful regeneration into the Ten-Tails. When Madara realised the situation, he attempted to rectify this. Despite Naruto and Killer B's attempt to destroy the Demonic Statue while in mid-transformation, it was successfully restored into the Ten-Tails, albeit in an incomplete form for a while before reaching its matured state.
However, the tailed beasts used in the Ten-Tails' recreation transfered bits of their chakra into Naruto prior to Obito carrying out the process as the Ten-Tails saw them supporting the young shinobi in spirit as they all have recognised him as the one that Hagoromo foretold. After Obito became its jinchūriki, the Ten-Tails assumed its true form to enact its host's desire while draining the chakra of those can it grasps in its branches. Eventually, through the combined effort of the Allied Shinobi Forces and Taka, all of the sealed tailed beasts were extracted from Obito's body and collectively decided to aid Naruto to fight against the revived Madara.
All of the tailed beasts, with the exception of Yin-Kurama, were eventually sealed back into the Demonic Statue of the Outer Path by Madara. However, the tailed beasts all left a portion of their chakra inside Naruto, continuing to support him against Madara and, later, Kaguya. After Naruto and Sasuke sealed Kaguya away, the tailed beasts were extracted from Kaguya and summoned to the real world along with Team 7 by Hagoromo and the deceased Kage. However, once Hagoromo sent back the deceased Kage's spirits, Sasuke placed all the tailed beasts in a genjutsu and imprisoned them in various Chibaku Tensei satellites, proceeding with his plans of leading the world through a revolution to do away with current shinobi systems, including killing all the current Kage and tailed beasts. He later summoned the tailed beasts to the Valley of the End during his battle with Naruto and absorbed their chakra into his Susanoo.
After Naruto became the victor in their rematch, he and Sasuke released the Infinite Tsukuyomi and the tailed beasts from the Chibaku Tensei. While Kurama and Gyūki return to their current jinchūriki, the other tailed beasts are living free with their own lives elsewhere, but all of them can still utilise the chakra they left inside Naruto as a "meeting ground", with Kurama looking over and managing the said meeting ground.

- In Naruto Shippūden the Movie: Bonds, it features the Zero-Tails. Despite having a numerical tail name and being referred to as a tailed beast in the movie, it is not an actual tailed beast as it has characteristics that are quite different from them.
- In Naruto the Movie: Blood Prison, there is a yōkai called Satori, who resides within the Box of Ultimate Bliss.
- In Road to Ninja: Naruto the Movie, Kurama has a Genjutsu World counterpart called the Black Nine-Tails (黒九尾, Kuro Kyūbi), who is sealed within the body of Naruto's alternate self, Menma. Menma creates and controls living entities composed of its chakra known as the Nine Masked Beasts.
- In Naruto Shippūden: Ninja Destiny 3, there are three masked beasts (仮面獣, kamenjū) featured in the game (like Matatabi and Isobu that have been featured in the game) that can be fought via Beast Battle Mode.
- In Naruto Shippūden: Dragon Blade Chronicles, there are five dragons known as the Genryū, each possessing one of the five chakra natures. If all the Genryū are combined, they become the Light Dragon.
- In Naruto Shippūden: Kizuna Drive, there is the Three-Headed Guardian Beast, guardian of Yumegakure which, like the tailed beasts, is a living form of chakra.
- In Naruto Shippūden: Ultimate Ninja Storm Revolution and two anime only episodes, like Mecha-Naruto, there is a Mecha-Kurama (メカ九喇嘛, Meka-Kurama), a mechanised version of Kurama.
- Shukaku, Matatabi, Gyūki, and Kurama are the only tailed beasts to be based on popular animal yōkai (such as tanuki, nekomata, ushi-oni, and kitsune respectively) from Japanese myth, while the others are original creations by Masashi Kishimoto, mixing together various elements from certain species of animals.
- While most of the tailed beasts have contemporary tails, Chōmei and Gyūki differ; Chōmei has one regular tail and six wings that make up its seven tails, while Gyūki has eight cephalopod limbs that serve as tails.
- According to some, the immense strength that the tailed beasts possess is tempered by their bestial nature, which restricts them from being intelligent enough to use it effectively, thus when the tailed beasts are sealed within humans, they are able to benefit from the knowledge of their hosts, giving them the ability to better utilise their powers. However, this was proven to be false.
- Despite all the tailed beasts gaining a name from Hagoromo, only some such as Son Gokū refer to themselves by that name on a regular basis. Others, such as Kurama and Gyūki, prefer to refer to each other by the number of tails each possess.
- Because of the moon's origin and it being the holder of the Ten-Tails' body, tailed beasts and subsequently their jinchūriki are effected by it, and much more so during a full moon.
- According to Gaara, Shukaku relishes the opportunity to kill anyone in sight at any time because of its innate rage and blood-lust, but especially so during the full moon.
- In the anime, Blue B, during his time as Gyūki's jinchūriki, noted that he would have trouble sleeping at night, especially during a full moon and at one point was shown to have to suppress a partial manifestation of Gyūki's tail after he had been staring at the full moon. Blue B was also shown to take sleep pills to help with this side-effect of being a jinchūriki.
- Several non-jinchūriki shinobi have been said to hold chakra levels, reserves or strength, comparable to that of a tailed beast. Such individuals include Kisame Hoshigaki, Hashirama Senju, Madara Uchiha, the Third Raikage, and the Fourth Raikage. In fact, Kisame has been given the moniker of Tailed Beast without a Tail (尾を持たない尾獣, O o Motanai Bijū, English TV: Tailless Tailed Beast). In addition, Madara has claimed that the power of his final Susanoo is comparable to that of a tailed beast.
- A tailed beast can "die" with its jinchūriki, if it is still sealed within them at the time of its host's death, but as living chakra the beast itself will be revived later.
- In the manga, before Taka began working with Akatsuki, Akatsuki was said to have seven tailed beasts. In the anime, when Taka is sent to capture Gyūki, the group has only six, the seventh missing beast being Saiken to make room for an additional anime-only arc.
- In the anime, the six tailed beasts that were used as Obito's Six Paths of Pain, all shared a voice actor with one of each other's respective jinchūriki.
- Throughout both Part I and II of the anime, how the tailed beasts speak has been very inconsistent. Kurama being the primary case, would speak with or without mouth movement.
