Kii Province

Kii Province (紀伊国), or Kishū (紀州), was a province of Japan in the part of Honshū that is today Wakayama Prefecture, as well as the southern part of Mie Prefecture. Kii bordered Ise, Izumi, Kawachi, Shima, and Yamato Provinces. The Kii Peninsula takes its name from this province.

During the Edo period, the Kii branch of the Tokugawa clan had its castle at Wakayama. Its former ichinomiya shrine was Hinokuma Shrine.

The Japanese bookshop chain Kinokuniya derives its name from the province.
