Arondizuogu// ^ⓘ (Aro-ndizuogu) is a town inhabited by the Aro people, an Igbo subgroup in Imo State of Nigeria. The Arondizuogu community is believed to have migrated from Arochukwu in the present Abia State to their current settlements in Imo State, which include the Okigwe, Ideato North and Onuimo local governments.

Arondizuogu is believed to have been founded in the mid-18th century through the forceful occupation and open massacre of the people of Umualaoma by Mazi Izuogu Mgbokpo and his brothers. Izuogu Mgbokpo, a slave merchant from Arochukwu, and who came to Awka in search of slaves, was harbored by a friend from Umualaoma. Izuogu Mgbokpo had two children and three brothers. The children were Uche and Awa while the brothers were Imoko and Njoku. Iheme was his chief servant and came from Isi-Akpu Nise, in Awka. Izuogu captured more slaves, whom he sold to European slave merchants. Arondizuogu people refer to themselves as "Izuogu na Iheme". Arondizuogu itself signifies "Aro of the people of Izuogu," in Igbo. Some of the people he enslaved kept his name even after they were freed from captivity.

Most of the wars over Arondizuogo were brought to an end by the patriarch of the host community, Ezerioha Udensi of Obiokwara, Obinihu, Umualaoma (i.e. Isuokpu). He organised the peaceful allocation or donation of lands to Arondizuogu, after concluding that the Arondizuogu people could no longer return to Aro Chukwu.

In the 19th century, Mazi Okoli Idozuka migrated from Isi-Akpu Nise to Arondizuogu. As a warrior, he expanded Arondizuogu's boundaries. He later changed his name to Okoro Idozuka, an Aro equivalent of his former name. He was a wealthy and ruthless slave trader but was also a great leader. Nwankwo Okoro was the first son of Okoro Idozuka, who at the age of 21 joined his father in the slave trade. When the British came, they made him a warrant chief. To this day, Arondizuogu is the biggest former Aro colony and a land of mainly immigrants.

Places of interest in Arondizuogu include Mazi Mbonu Ojike Cottage (village home of Nigeria's late "Boycott King"); Uno Ogologo (a safe house built in 1887 for hiding children during the slave trade era); the Stone Palace (a storehouse erected by late Chief Green Mbadiwe, West Africa's first millionaire, for his father, Umualaoma Nkwo Ochie); Mbadiwe Odum; Ngeze stream; Ogbuti Ezumezu (visitor's chamber of Ikeji musician Pericoma Okoye); LN Motel Plaza, Home Diamond Hotel; National High School, Arondizuogu (pioneer model school built by Mazi Nwosu Elele Igwiloh and commissioned in 1951); Iheme Memorial Secondary School (a second model school commissioned in 1951); Palace of The People (country home of Nigerian politician K. O. Mbadiwe, commissioned by Nigeria's prime minister Abubakar Tafawa Balewa in 1965); Upiti rice fields; Obi Omenuko, homestead of Igwegbe Odum; and Ngene Okwe, a natural spring.

Ndi Izuogu live in many local government areas in Imo State. Although they have almost the same dialect as the group of Igbos in Anambra State, apart from Ndi Uche (descendants of Izuogu's first son) they still retain a slightly different dialect. Arondizuogu, which is made up of 20 villages, inhabits three Local Government Areas. The local governments inhabited include Okigwe, Ideato North, and Onuimo.

Arondizuogu is a group of sprawling communities with the largest area being Umualaoma town (formerly Isiokpu).

Instituted in 1948, ‘Arondizuogu Day’ is an annual end-of-year convention of people of Arondizuogu descent at home and abroad. It is a day set aside to celebrate achievements, review challenges, and generally foster patriotism in the community. For the culture–loving people of Arondizuogu, the day is a unique annual homecoming that they celebrate with much aplomb comparable only to their popular Ikeji Festival, which is touted to be “the greatest carnival of masks and masquerades in Africa”.^{[citation needed]}
