The Battle of Kotesashi (小手指ヶ原の戦い, Kotesashi-gahara no tatakai) was part of the decisive Kōzuke-Musashi Campaign during the Genkō War in Japan that ultimately ended the Kamakura Shogunate.

Fought in present-day Tokorozawa, Saitama on May 11, 1333, it pitted the anti-shogunate imperial forces led by Nitta Yoshisada against the pro-Shogunate forces of the Hōjō Regency led by Sakurada Sadakuni.

In the morning of the May 11, the Imperial forces crossed the river and opened their attack with an archery barrage.

This was followed by both sides sending in their mounted warriors in multiple waves throughout the day.

The results were indecisive with both forces drawing away at the day's end to set up camp and rest.
