Yoruba language is the most widely spoken African language outside Africa.

Yoruba is classified within the Edekiri languages, which together with Itsekiri and the isolate Igala form the Yoruboid group of languages within the Volta-Niger branch of the Niger-Congo family. The linguistic unity of the Niger-Congo family dates to deep prehistory, estimates ranging around 15 kya (the end of the Upper Paleolithic).[6] In present day Nigeria, it is estimated that there are over 40 million Yoruba primary and secondary language speakers and several other millions of speakers outside Nigeria making it the most widely spoken African language outside Africa.
