Calle 13 is a Puerto Rican hip-hop duo formed by two brothers who call themselves Residente (lead singer, writer) and Visitante (pianist, vocals, writer). Their sister (Ileana, aka PG-13) has contributed to several of their songs. They named themselves Calle 13 after the area where they grew up in Trujillo Alto.

The duo rose to fame in 2005 with two back-to-back hits on Puerto Rican radio stations, first one being Se Vale To To and Atrevete-te-Te!. Another song, the controversial Querido FBI, that was not intended to be on their first release was written by the group's lead singer after the death of Filiberto Ojeda Ríos (leader of Puerto Rican revolutionary group, Los Macheteros). The duo was criticized by those who believed the lyrics promoted violence against the authorities, but the group insisted the song wasn't meant to be taken literally.

After their rise to fame, the duo was sought by other reggaeton artists, and they collaborated with artists such as Voltio in the song Chulin Culin Chunfly, and with the Three 6 Mafia in the remix, singing or co-writing songs. At the end of 2005, they released their first album, Calle 13, to much critical praise.

In December 2005, the Governor of Puerto Rico, Anibal Acevedo Vilá, admitted to listening to the duo when his son got him some of their songs on his iPod. This prompted him to invite them to La Fortaleza and to have them record a song against shootings bullets in the air during New Years Eve celebrations.

2006 was an even better year for the duo. So far, they have had three more smash hits on Puerto Rican radio stations, including the colombian cumbia style song Atrevete-te-Te!, Japón, and Suave. The group also had their first big concert on May 6, 2006 at the Jose Miguel Agrelot Coliseum.

The two brothers that form the duo are as different as brothers could be.
