Igwe Orizu I (Eze Ugbonyamba; born 1881-1924) was the 18th Obi of Otolo and the Igwe of Nnewi kingdom. He was the traditional supreme ruler and spiritual leader in Nnewi, an Igbo city in Eastern Nigeria. Eze Ugbonyamba was crowned the King of Nnewi and he took the ofo of Nnewi after his fathers death in 1904. He was a member of the Nnofo Royal lineage and the successor to his father Igwe Iwuchukwu Ezeifekaibeya. Igwe Orizu I (Eze Ugbonyamba) died in 1924 and was succeeded by his first son Igwe Josiah Orizu II . One of remarkable events of his reign was the arrival of the British in 1905.

Eze Ugbonyamba was a young man when his father died, the British army led by Major Harry Moorhouse and Hugh Trenchard entered Nnewi in the same year. The British agreed to support the young King and Nnewi laid down arm soon afterwards. It was also in 1904 that Trenchard was involved in bringing Igboland under British control.

It was Eze Odumegwu, supported by some of his people with courage, that came forward to Nkwo Nnewi in December 24, 1904 to welcome the new master, bringing presents of food and such other things as previously directed. His young cousin, Eze Ugbonyamba, as well as some other Obis, was not in attendance. The Major was very impressed with the reception and accorded therefore to Eze Odumegwu the headship of the entire Nnewi town. He declined to accept the offer, saying that there was a higher Obi than himself. He promised to come along at the next meeting with the young Obi to whom the honor belonged.

Initially many of the inhabitants refused to surrender weaponry to the British and Trenchard's political advisor, R M Heron, arranged for the destruction of the houses of those who harboured weapons. In light of this policy, many guns and other arms were surrendered to Trenchard's soldiers at Nkwo Nnewi where they were destroyed. During this time the Igbo nicknamed Trenchard Nwangwele, meaning young lizard in Igbo, on account of his figure.
