The name Obinna originated from the Igbo culture of southeastern Nigeria. It is believed to have roots dating back to the 9th century AD or earlier. Obinna is derived from the Igbo words "Ọbị" meaning "heart" and "nna" meaning "father." Thus, the name translates to "father's heart" or "the heart's father."
