Indigenous knowledge is the knowledge that indigenous peoples are leading their livelihood and also they learnt it from the actual practices during their day to day life. Among the different aspects of Indigenous knowledge, one is Indigenous ritual; which is conducted by indigenous peoples for very different reasons. Traditionally the Indigenous knowledge were considered as worthless and anybody have had criticizing it. But, currently the reality is promulgated by different scholars as the indigenous knowledge is very crucial in day to day life of indigenous peoples. The research methodology was mainly qualitative research method. The primary data were gathered through observation, FGDs, key informants’ interviews, questionnaire and informal conversations. Secondary sources were gathered from the district offices and internet. The Uke ritual is the indigenous ritual celebrated by children’s whose age are less than 16 years. It is the ritual celebrated with the bread anointed with butter and milk on July 5/12 E.C/July 12/19 in G.C. This ritual has a lot of purposes like commemorating the children’s day, consolidating their relationship, training them about their future career, publicizing their right, etc. The political and religious (protestant) domination faced the people during the past regimes contributed much to the weakening of Uke ritual. Here, it is also possible to say that before the commencement of Universal Declaration of Human Rights in 1948, the Oromo people have a culture that respects and give guarantee for human right in general and that of children’s right in particular.
