"33" is a song recorded by Argentine singers Lali and Dillom, included in Lali's sixth studio album No Vayas a Atender Cuando el Demonio Llama (2025). It was written by both artists alongside BB Asul, Juan Giménez Kuj, Mariano Napoli, Mauro De Tommaso, and Don Barreto, while production was handled by the latter two. Conceived as a track that blends pop rock, alternative rock influences, and electronic elements, its lyrics explore themes of maturity, transformation, and reflection on the passage of time—symbolized by its title, which references Lali's age at the time of releasing the song. The song was released as a single on 24 April 2025 through Sony Music Argentina as the album's fourth single.
