Isu is a local government area in the Imo State of Nigeria. Its headquarters are in the town of Umundugba. Other communities are Amandugba, Ekwe, Uburu Ekwe, Isunjaba, Amurie Omanze, Ebenator Ekwe and Oboro Amurie.The name comes from the Isu people, a subgroup of the Igbo people.

Amandugba and neighboring Umundugba were originally one town. Both communities have suffered from a horrid water supply from streams and brooks that often evaporate at an alarming speed. The mentioned bodies of water also serve as breeding grounds for malaria-borne mosquitoes and are sources of diseases such as cholera, diarrhea, dysentery, and parasites such as the guinea worm and the tape worm. A recent project by Africa We Care, a charity, has started to develop a supply based on a bore-hole.

A local school in the area is known as the Missionary Institute of God’s Image (MIGI) German Language School. This school is located in Amurie Omanze in Isu Local Government Area. The MIGI German Language School has the recognition of the Imo State Ministry of Tertiary Education. German language is being taught there for students who wish to study in Germany.
