"Iguana" is a song by Romanian singer Inna. It was digitally released on 30 November 2018 as the second single for her sixth studio album Yo (2019) by Global Records and Roc Nation, although having already been made available for streaming and airplay earlier that month. It was written by Inna and Cristina Maria Chiluiza, while production was solely handled by David Ciente. Musically, the uptempo track has been described as being club and salsa-influenced, extending Inna's change in direction introduced with "Ra" (2018). The song's lyrics are in Spanish and see Inna discussing jealousy and lovesickness.
