His Majesty The King's Christmas Message (Spanish: Mensaje de Navidad de S.M. el Rey) is the annual broadcast by the Spanish monarch on Christmas Eve. It has taken place every year since 1975, the first year of Juan Carlos I's reign. The speech is aired on all Spanish TV channels.^[1]

The message typically combines a chronicle of that year's major events, with specific focus on politics, economy, culture and social affairs, and also the sovereign's own personal feelings on Christmas. It is usually not broadcast until 21:00 on 24 December.

During his reign, King Juan Carlos I usually covered the main problems of the nation, such as ETA. In 2004, the speech was highly related to the Madrid train bombings earlier that year; in 2006 the King discussed the need to become a united nation against terrorism (in implicit support of Prime Minister José Luis Rodríguez Zapatero's anti-terrorist policies) and he mentioned the increasing force of immigrants in Spain and appreciated their contribution to the economy.

• During his reign, Juan Carlos began his speeches with the phrase "La reina y yo" ("The Queen and I"). This was commonly considered his main catchphrase and as such has often been parodied by media. A comic strip in El Jueves magazine about the monarchy takes his title from this. In a departure from his father's custom, King Felipe VI started his 2015 speech with the phrase "Buenas noches" (Good night).^[2]
• The King's speech has been parodied in many television shows such as Buenafuente [es].
• Mariano Rajoy's speech on the occasion of Fiesta Nacional de España was criticized by the Left because it bore a resemblance to the King's Christmas speech. Rajoy delivered his message seated near the flag of Spain and in a medium shot, just as royal speeches usually are.
