The Battle of Gayaza Hills or the Battle of Kajurungusi (Kiswahili: Mapigano ya Kajurungusi) was a conflict of the Uganda–Tanzania War that took place in late February 1979 around the Gayaza Hills and Lake Nakivale in southern Uganda, near the town of Gayaza. Tanzanian troops attacked the Ugandan positions in the hills, and though they suffered heavy casualties in an ambush, they successfully captured them by the end of the day.
