Kuki Takanaga (died 1190) was the daimyo of the Yamauchi clan from c. 1188 until his death, succeeding Yamauchi Kaneyo. In 1190, he proved to be fiercely loyal to the Kamakura Minamoto, as he was one of the few daimyo who sided with Minamoto Yoritomo in the civil war with Emperor Go-Toba's faction. Kuki Takanaga paid the price for his bravery and loyalty, dying with the destruction of his clan.
