"A la Primera Persona" (English: To the First Person) is a love song recorded by the Spanish singer-songwriter Alejandro Sanz. It was released as the first single from his album El Tren de los Momentos (2006). The song reached the number-one spot on the Billboard Hot Latin Tracks and Latin Pop Airplay charts.

The music video of the song starts with a scene in which a train is seen passing during sunrise. Then, Alejandro is seen walking alone on the street. He then picks up a newspaper from a garbage can and starts to read it. He continues to walk and suddenly sees some objects lying in the middle of the street. He picks up a guitar, which is also thrown there. It is then revealed that he owns the objects, and that his girlfriend was the one who threw them there after an argument with him.
