Hata (秦氏, lit. "Qin dynasty clan") was an immigrant clan active in Japan since the Kofun period (250–538), according to the history of Japan laid out in Nihon Shoki.

Hata is the Japanese reading of the Chinese surname Qin (Chinese: 秦; pinyin: Qín) given to the State of Qin and the Qin dynasty (the ancestral name was Ying), and to their descendants established in Japan. The Nihon Shoki presents the Hata as a clan or house, and not as a tribe; only the members of the head family had the right to use the name of Hata.

The Hata can be compared to other families who came from the continent during the Kofun period: the descendants of the Chinese Han dynasty, through Prince Achi no Omi, ancestor of the Aya clan, the Sakanoue clan, the Tamura clan, the Harada, and the Akizuki clan, as well as the descendants of the Chinese Cao Wei dynasty through the Takamuko clan.^{[citation needed]}
