Yamauchi Kazutoyo (山内 一豊 （やまうち かつとよ）) also spelled Yamanouchi (1545/1546? – November 1, 1605), was born the son of Yamanouchi Toyonao in Owari Province at the end of the Sengoku period of Japan. Kazutoyo held the title of Tosa no kami.

Kazutoyo built Kōchi Castle. His life spanned the closing years of the Sengoku period, the Azuchi-Momoyama period, and the beginning of the Edo period.

Just four years after he became Lord of Tosa, Kazutoyo died without issue aged around 60, and was succeeded as Lord of Tosa by his nephew Tadayoshi.

In drama

The 45th NHK Taiga drama (2006) is a dramatization of the life of Kazutoyo, with his wife Chiyo as the central character. Kōmyō-ga-tsuji: Yamauchi Kazutoyo no Tsuma stars Nakama Yukie as Chiyo.

The story is by Shiba Ryōtarō.
