Naming is an important aspect of the Yoruba culture. The importance of naming has been eroded by civilization, Westernization, foreign religions, and globalization. Names are identity, and it is a means of social arrangement, social engagement, and social structure among the Yoruba of West Africa. Names are associated with place of birth, period of birth, family background, important events, days, and others. Many people have been able to retrace their origin, historical records, and family background through their family names. Names have opened opportunities for many. The Yoruba use names to determine suitability for marriage, association, friendship, and assumption of important traditional posts. The Yoruba naming could be described as cultural heritage. Differential Association Theory propounded by Edwin Sutherland was used in this study. Differential Association Theory emphasizes communication and learning processes as mechanisms of corruption in good manners. Secondary sources of data were used to collect data on differences, importance, sources, and reasons for the disappearance of indigenous names such as textbooks, the internet, and others. The survival of the Yoruba race impinges on the survival of its culture including naming culture. Bad aspects of Westernization, modernization, and globalization should be dropped to protect naming - an important cultural heritage among the Yoruba. Therefore, this paper suggested dropping any religious or foreign names such as Faith, Rashidat, Michael, and others. The Yoruba should retain their first and last indigenous names such as Adeyinka, Olu, Fayemi, Ogunlowo, and others.
