Barón Rojo (Spanish pronunciation: [baˈɾon ˈroxo]) is a Spanish heavy metal band that achieved international success in the 1980s. The band is led by siblings Carlos and Armando de Castro, previously from the band Coz, and is considered one of the most important representatives of Spanish hard rock. Barón Rojo in Spanish means "Red Baron", the name of the band being an homage to Manfred von Richthofen; the 1981 eponymous song "Barón Rojo" is about him.
In 2017, they were ranked number 18 on Rolling Stone's "50 Greatest Spanish rock bands".
