The Otuho people, also known as the Lotuko, are a Nilotic ethnic group whose traditional home is the Eastern Equatoria state of South Sudan.

They engage in some subsistence agriculture; their main crops are sorghum, ground nuts, simsim (sesame), and maize in the plains, or telebun, dukhn, sweet potatoes, and tobacco in the hills.

The chief god of the Otuho is called Ajok; he is generally seen as kind and benevolent, but can be angered.

[3][failed verification] In Otuho mythology he once answered a woman's prayer for the resurrection of her son.

Ajok was annoyed by his actions and swore never to resurrect any Otuho again, and in this manner, death was said to have become permanent.
