Oyi is a City and a Local Government Area (LGA) in Anambra state, Nigeria. It is home to the Oyi people. The towns that make up the local government are Nkwelle-Ezunaka, Awkuzu, Ogbunike, Umunya and Nteje. The origin of Oyi people is the same for all the "OLU" sub group of the Eri-Awka Igbo. The Olus are the distinct river-side Igbo people of the lower Anambra plain (Anambra River Basin), encompassing the entire old Anambra Division of the 1920s to the 80s, parts of today's Awka North LGA of Anambra State and the excision of the former Uzo-Uwani LGA of now Enugu State.
Oyi people, like other Olu people, are usually tall, care-free and socially progressive people. Oyi practice a Jewish-like Kabbalah (Cabbala) system of self-actualisation which is embedded in the apical Nze-na-Ozo tradition of "Onye chizue; o bulu Mmoo, bulukwa Mmadu". Translated, this simply says that the Ozo initiation is a threshold vista of self-distinction that transforms the initiates into both man and spirit or "spirit-man". Popular place in Oyi include: Ogbunike Caves, Umunya Aparition Site and Urunda Crescendo.
