IV of Spades (stylized in all caps; pronounced "four of spades"[5]) was a Filipino rock band from Metro Manila, Philippines, consisting of vocalist, bassist and keyboardist Zild Benitez, vocalist and lead guitarist Blaster Silonga, and drummer Badjao de Castro.

Unique Salonga, Benitez's churchmate who was already writing his own music, was later recruited to become the band's lead singer.

Blaster's father, Allan Silonga, is a member of 90s band Kindred Garden, which evolved after a while as k24/7, and the singing group Daddy's Home which finished third in The X Factor Philippines.

IV of Spades signed to a record label and released their debut single "Ilaw sa Daan" under Warner Music Philippines.
