Omu-Aran the Head Post of Ìgbómìnà land, is a town in the Nigerian state of Kwara. It originated from Ife and currently the local government headquarters of Irepodun Local Government Area. Omu-Aran is 86.3km from Ilorin, Kwara State Capital, along Ilorin-Kabba Federal Highway.

Omu-Aran was founded over 500 years ago. The community was founded due to the migration of people from Ilé-Ifẹ̀. There was a drought in Ile-Ife. To know the cause of the drought, the oracle was consulted. The oracle said Ife was over-crowded and therefore some people had to leave. Some princes were selected to migrate to other places and were given the symbol of authority. One of the selected princes was Olomu-Aperan, the founder of Omu-Aran. Omutoto or Omitoto, one of the wives of Olofinaiye Oduduwa was the mother of both Olomu Aperan and Owa Ajibogun, the founder of Ijesha land. This tradition is accepted in Ilesha and Ile Ife today. Olomu Aperan became the custodian of the Ogbo because of the Royal War title Esinkin. However, Ogbo, a symbol of authority was the property of the aboriginal people of Ile Ife. The Ogbo was also the symbol of oneness among the council of Elders in Ile Ife. Through the Ogbo the council could unknot every difficult problem. Hence, the council was called the Council of Ologbomona. Olomu Aperan left Ile-Ife with the Ogbo and found various Kingdoms.

Omu-Aran is made up of people from different backgrounds who migrated to the present site of the town. Omu-Aran became the headquarters of Irepodun LGA on 24 August 1976.

Due to the vegetation of the area, Omu-Aran residents were predominately farmers. They were also famous in handicraft like basket weaving and blacksmith works.
