Edgardo José Martín Santiago Valenciano, better known as simply Gary Valenciano (shortened to Gary V.), is a Filipino musician, composer, actor, producer, and gospel singer who is best known for many songs, especially those that became theme songs for movies. His energetic dance moves also garnered him the nickname "Mr. Pure Energy."

Born in the suburb of Santa Mesa in Manila on August 6, 1964, he is the sixth of Vicente Valenciano and Grimilda Santiago Ortiz’s seven children. Santiago Ortiz is a Puerto Rican woman of Italian descent who became a popular opera singer in Manila during the 1960s, and her love for music passed down to her son, Gary. He took his primary and secondary studies in La Salle Greenhills. It was during his high school days, while being on a brief stint the musical group Kundirana, that he devoted himself to music.
