Temari (テマリ) is the oldest child of the Fourth Kazekage, making her the older sister of Gaara and Kankuro. Like her siblings, Temari is seen less often than the other main characters in the series. Temari is generally overbearing, if not crude, toward those around her, rarely afraid to speak her mind. Temari does have a caring side though and is not above showing concern for others. She seems to value peace, as she questioned the reasoning of starting a war with Konoha. In Part II, Temari acts as a liaison between Sunagakure and Konoha to prepare for the next Chunin Exams. Like Kankuro, her relations with Gaara have greatly improved, though she isn't as close as the two brothers. When Gaara was captured by Akatsuki, Temari hurried back to the village to save her brother, and when Kankuro was poisoned, she watched over him until he was ready to move himself.

Many of Temari's appearances are associated with Shikamaru. Though they are opponents during the Chunin Exams, they come to each others' aid at different point in Part I. When Naruto returns to Konoha at the start of Part II and sees the two of them walking together, he asked them if they were on a date, which both of them denied.
