Spain–Venezuelan relations are the bilateral relations between the Kingdom of Spain and the Bolivarian Republic of Venezuela. Both nations are members of the Association of Spanish Language Academies and the Organization of Ibero-American States.

¿Por qué no te callas? is a phrase that was uttered by King Juan Carlos I of Spain to Venezuelan President Hugo Chávez, at the 2007 Ibero-American Summit in Santiago, Chile, when Chávez was repeatedly interrupting Spanish Prime Minister José Luis Rodríguez Zapatero's speech. Following international attention, the phrase became an overnight sensation, gaining cult and meme status as a mobile-phone ringtone, spawning a domain name, a contest, T-shirt sales, a television program and YouTube videos.
