Taira no Kiyomori (平 清盛?, 1118 – March 20, 1181) was a military leader of the late Heian period of Japan. He established the first samurai-dominated administrative government in the history of Japan.

After the death of his father Taira no Tadamori in 1153, Kiyomori assumed control of the Taira clan and ambitiously entered the political realm in which he had previously only held a minor post. In 1156, he and Minamoto no Yoshitomo, head of the Minamoto clan, suppressed the Hōgen Rebellion. This established the Taira and Minamoto as the top samurai clans in Kyoto. However, this caused the allies to become bitter rivals which culminated three years later during the Heiji Rebellion in 1159. Kiyomori, emerging victorious with Yoshitomo and his two eldest killed, was now the head of the single most powerful warrior family/clan in Kyoto. However, his clan's power and influence in the provinces at this time is a matter of debate. Kiyomori showed mercy and exiled a few of Yoshitomo's sons, including Yoritomo, Noriyori, and Yoshitsune – a benevolence that would turn out to be the Taira clan's downfall later on.
