Imagawa Yoshimoto (今川 義元, 1519 – June 12, 1560) was a Japanese daimyō (feudal lord) of the Sengoku period.

[2] In 1542, Yoshimoto began his advance into Mikawa Province, in an effort to fight the growing influence of Oda Nobuhide in that region, but was defeated in the 1542 Battle of Azukizaka.

Later, Yoshimoto left the clan's political affairs in Ujizane's hands, in order to focus on dealing with the advance westward into Mikawa and Owari.

In the summer of 1560, after forming a three-way alliance with the Takeda and the Hōjō, Yoshimoto headed out to the capital with Matsudaira Motoyasu (later known as 'Tokugawa Ieyasu') of Mikawa in the vanguard.

[10] Two Oda samurai (Mōri Shinsuke and Hattori Koheita) ambushed and killed Yoshimoto in the village of Dengakuhazama.

Yoshimoto has several graves; his body itself is buried at Daisei-ji, a temple in the city of Toyokawa in modern Aichi Prefecture.

In Samurai Warriors 5, however, where he fights with a warhammer and his ancestral katana Samonji, he is instead portrayed as an arrogant but effective leader who is a persistent threat to the young Oda Nobunaga, even defeating him in combat in one battle and forcing the Oda army to withdraw, before his eventual defeat at Okehazama.

In this version, instead of dying Yoshimoto is spared and later installed as a figurehead Shōgun to legitimize Nobuna's claim to Kyoto.

In Sengoku Basara game and anime series, he was shown to be a weak leader, using his vassals as decoys while trying to retreat.
