Yuki Nagato (長門 有希, Nagato Yuki^?) is a fictional character in the Haruhi Suzumiya franchise. She is initially portrayed as an introverted, taciturn bibliophile. She is actually an artificial human created by the Data Overmind (情報統合思念体, Jōhō Tōgō Shinen-tai^?, translated as Data Overmind in the novels, but as Data Integration Thought Entity in the anime), and possesses supernatural powers as a result. She did not act to join Haruhi Suzumiya's SOS Brigade, instead coming with the room that Haruhi appropriated, and then being listed on the forms Kyon filed to establish the club. She observes and takes part in club activities on the behalf of the Entity while still being the only member of the Literary Club. In addition, she is present to ensure that Haruhi does not use her godlike powers, and aids the other Brigade members in stopping forces that cause her to do so. The alternate Yuki established in the fourth light novel, The Disappearance of Haruhi Suzumiya, is the main character of the spin-off manga The Disappearance of Nagato Yuki-chan.

Apparently Yuki has extremely pale skin. There are numerous times in the original light novels where Kyon describes her face, neck, hands, or fingers (as she flips the pages of the book she is reading) as "white". Also, Kyon always comments on Yuki's uncanny ability to walk "soundlessly" (this can be seen in the anime when Yuki is exploring a public library with Kyon who appears puzzled by it). Yuki is attractive enough to earn an "A-" grade from Taniguchi and, as Taniguchi states, has a lot of secret admirers. In The Disappearance of Haruhi Suzumiya, when Kyon came face to face with Yuki in a twilight realm (here she is simply a normal, shy girl) blushing in front of him, he was stunned by her and even felt for a moment that it would be good to stay in this realm and join the Literature Club for good. She initially wears glasses, but forgets to regenerate them after they are broken while she is protecting Kyon from Ryoko. When she realizes she no longer has them, Kyon tells her she looks cuter without them, prompting her to leave them unregenerated.
