Kawachi Province (河内国 Kawachi no kuni?) was a province of Japan in the eastern part of modern Osaka Prefecture. It originally held the southwestern area that was split off into Izumi Province. It was also known as Kashū (河州?).
Kawachi was divided into three counties (地区 chiku?): northern (北河内 Kita Kawachi?), central (中河内 Naka Kawachi?), and southern (南河内 Minami Kawachi?).
