The Battle of Komaki and Nagakute (小牧・長久手の戦い, Komaki-Nagakute no Tatakai), also known as the Komaki Campaign (小牧の役 Komaki no Eki), was a series of battles in 1584 between the forces of Hashiba Hideyoshi (who would become Toyotomi Hideyoshi in 1586) and the forces of Oda Nobukatsu and Tokugawa Ieyasu.

The conflict was resolved when Hideyoshi and Ieyasu agreed to exchange hostages; Ieyasu sent his son (Ogimaru) to Hideyoshi, who in turn sent his own sister (Asahi no kata) and mother (Ōmandokoro) to Ieyasu.
