Sue Harukata (陶 晴賢, 1521 – October 16, 1555) was a samurai who served as a senior retainer of the Ōuchi clan in the Sengoku period in Japan.

[1] However, when Ōuchi's troops lost heavily in 1542, Yoshitaka's interest in war faded, and he began to incline to cultural activities.

[1] The next year Harukata secured the control of the Ōuchi clan by making the adopted son of Yoshitaka, Ōuchi Yoshinaga (who was Ōtomo Haruhide, the half-brother of Ōtomo Sōrin), the head of the clan.

Subsequently, he conducted a large military expansion, but this led to discontent among the retainers of the Ōuchi clan.

In the Battle of Oshikibata, Sue Harukata's retainer Takagawa, was defeated by Mori Motonari.
