Mikoto Uchiha

was a Konohagakure shinobi as well as the mother of Itachi Uchiha and Sasuke Uchiha and the wife of Fugaku Uchiha.

Background
While little is known of her career as a kunoichi, she was presumably skilled enough to have been promoted to the rank of jōnin. After marrying Fugaku Uchiha, she settled down to become a housewife, raising their sons Itachi and later Sasuke. She was the first to know about her friend Kushina Uzumaki's delicate pregnancy, and expressed her desire that their sons (Sasuke and Naruto Uzumaki respectively) would be good friends.

During the Nine-Tails' Attack on Konoha, Itachi noted that she and Fugaku were noticably absent before the beast struck. What she was doing is currently unknown.

Despite her concentration on domestic pursuits, it was presumed she was also very trustworthy to be at Fugaku's side when the latter began plotting a coup d'etat against the Senju-led government of Konohagakure. She was later found dead with her husband during the Uchiha clan massacre, killed by Itachi.

Personality
Mikoto was a very gentle and kind woman. She cared about her sons deeply, and knew how to help them with their problems. She also gave Sasuke advice and tried to reassure him about Itachi. She seemed to like Sasuke better where her husband seemed to prefer Itachi. She was a very good mother, seeing as how Sasuke was able to talk to her better than his father. At one point, in order to cheer Sasuke up, she says that when she and Fugaku are alone, Sasuke is all he talks about. Although she was Itachi's mother, she like other clan members, grew suspicious of his strange behavior.

Trivia

 * In the character introduction of the Viz Media translation of Volume 25, instead of the name "Mikoto," she is simply credited as "Sasuke's Mother."
 * It is safe to say that Itachi and Sasuke get most of their looks from their mother rather than their father, except for the creases under Itachi's eyes.
 * Even though she is a Jōnin, Mikoto seems to be more focused in her duties as a housewife, similar to Yoshino of the Nara clan.
 * means precious and nobility and is used as a title for Japanese gods.
 * According to the second official databook, Mikoto is not a born Uchiha and does not have the Sharingan because of this.
