Iboshi Hokuto (違星 北斗; 1901 – January 26, 1929) was a Japanese Ainu waka poet and social activist. He devoted his life to improving the standing of the Ainu people, expressing his ideas as tanka in newspapers and magazines and influencing the Ainu youth of the time. He also circulated around the Ainu kotan (villages) of Hokkaido, preaching of the need for unity and the formation of an Ainu identity. Along with Yaeko Batchelor and Takeichi Moritake, Iboshi is counted as one of the "Three Great Ainu Poets" (アイヌ三大歌人). He has been called the "Takuboku of the Ainu".
