Johannes Ockeghem was a Franco-Flemish composer and singer of early Renaissance music. Ockeghem was the most influential European composer in the period between Guillaume Du Fay and Josquin des Prez, and he was—with his colleague Antoine Busnois—the leading European composer in the second half of the 15th century. He was an important proponent of the early Franco-Flemish School.

Renaissance music is traditionally understood to cover European music of the 15th and 16th centuries, later than the Renaissance era as it is understood in other disciplines. Rather than starting from the early 14th-century ars nova, the Trecento music was treated by musicology as a coda to Medieval music and the new era dated from the rise of triadic harmony and the spread of the contenance angloise style from Britain to the Burgundian School. A convenient watershed for its end is the adoption of basso continuo at the beginning of the Baroque period.
