Ogbanie is a term from Igbo folklore, referring to a spirit or entity believed to be the reincarnation of a child who died before being properly named. These spirits are thought to cause mischief and harm, often leading to the death of their mothers during childbirth or illness. In some beliefs, they may possess the ability to take on human form and live among people, causing chaos. Dealing with an ogbanie often involves rituals and offerings to appease the spirit.
