Kitahata (北波多村, Kitahata-mura) was a village located in Higashimatsuura District, Saga Prefecture, Japan.
Kitahata was established in 1889 (Meiji 22) as a union of small hamlets.
On January 1, 2005, Kitahata, along with the towns of Chinzei, Hamatama, Hizen, Kyūragi, Ōchi and Yobuko (all from Higashimatsuura District), was merged into the expanded city of Karatsu.
The town hosts the Karatsu City Hospital Kitahata.
It also runs the Kitahata Furusato Summer Festival in July.
