Juan Manuel Hermenegildo de la Luz Olivares (4 April 1760 – 1 March 1797) was a Venezuelan composer during the colonial era.
Olivares was born in Caracas. As a child, he studied under Don Ambrosio Carreño. In 1784, he began teaching in Caracas, and the same year, Pedro Ramón Palacios y Sojo entrusted to him the direction of the Academia del Oratorio de San Felipe de Neri, a position he held until his death; he also became organist for the academy's church, the Basílica de Santa Teresa.
On 11 May 1789, he married Sebastiana Velásquez in Caracas at the Church of San Pablo Ermitaño, which stood where the Municipal Theater now stands. Padre Sojo was the priest. Olivares was the caretaker and teacher of Lino Gallardo. He died in El Valle, Caracas.
