Ricardo Horacio Iorio (25 June 1962 – 24 October 2023) was an Argentine heavy metal singer and bassist.

Iorio was one of the founders of V8 (1979–1987) and later founded the band Hermética (1988–1994). He was the singer and main composer for Almafuerte from 1995 until its dissolution in 2016. His songs were urban stories dealing with the life of the lower classes, as well as Argentine 'metalheads'. Even though he played bass with every band he formed, he chose Beto Ceriotti to be the new bassist of Almafuerte, remaining as the singer and main lyricist of the band.

Extremely nationalist, Iorio continuously proclaimed in his songs and in the media his pride in being Argentine and in Argentine history, and mixed native music styles such as tango, Indian and gaucho culture with the heavy metal base of Almafuerte.
