Kira Mitsusada (died 1384) was lord of Saijō Castle in Mikawa Province, eldest son of Kira Mitsuyoshi and founder of the Saijō Kira branch. He joined Ashikaga Takauji's rising with his father, and in the Kannō Disturbance fought for Ashikaga Tadayoshi; after Tadayoshi's death he allied with the Southern Court and briefly seized Kyoto.

In 1360 he blocked Hatakeyama Kunikiyo's retreat at Yahagi in Mikawa, but submitted to the shogunate in 1361. From 1363 he served 21 years as a hikitsuke headman, and he died in 1384.
