Chief Sunday Adeniyi Adegeye MFR (born 22 September 1946), known professionally as King Sunny Adé, is a Nigerian jùjú singer, songwriter and multi-instrumentalist. He is regarded as one of the first African pop musicians to gain international success, and has been called one of the most influential musicians of all time.

Sunny Adé formed his own backing band in 1967, eventually known as his African Beats. After achieving national success in Nigeria during the 1970s and founding his own independent label, Sunny Adé signed to Island Records in 1982 and achieved international success with the albums Juju Music(1982) and Synchro System (1983); the latter garnered him a Grammy nomination, a first for a Nigerian artist. His 1998 album Odu also garnered a Grammy nomination. Sunny Adé currently serves as chairperson of the Musical Copyright Society of Nigeria.

Sunny Adé was born in Osogbo to a Nigerian royal family from Ondo and Akure, thereby making him an Omoba of the Yoruba people. His father was a church organist, while his mother, Maria Adegeye (née Adesida), was a trader. As a member of the Adesida dynasty, his mother’s relatives included her father Oba Adesida I (who ruled Akure for 60 years) and would later include her nephew and Adé’s cousin, Oba Adebiyi Adegboye Adesida Afunbiowo II, a future king of Akure.
