Calibre 50 is a regional Mexican band. Formed in Mazatlán, Sinaloa in 2010 by Edén Muñoz, the band has had several lineup changes, with the current roster consisting of lead vocalist Tony Elizondo, diatonic accordionist José Mario "Marito" Gastélum, twelve-string guitarist Oscar Arrendondo, sousaphonist Alejandro Gaxiola, and drummer Erick García.

The band has won four IHeartRadio Music Awards and three Lo Nuestro Awards, and is one of the most streamed regional Mexican acts on streaming platforms. Their musical style employs a fusion of norteño and banda music, known as norteño-banda, with low notes played by a sousaphone instead of a bass guitar as is traditional in norteño music.

2010: Formation and Renovar o Morir
Before forming Calibre 50, musician Edén Muñoz had been a member in the regional Mexican band Colmillo Norteño and released three studio albums while in the band. In 2010, Muñoz left Colmillo Norteño and formed a new band, Puro Colmillo Norteño, which was later retitled to Calibre 50 after legal disputes with Colmillo Norteño occured.

The band, consisting of Muñoz as the lead vocalist and accordion player, guitarist Augusto Guido, tubist Armando Ramos and drummer Martín López, chose the name Calibre 50, which refers to the 12 millimeter caliber firearms cartridge. The band would play at local parties and restaurants, until the track "El Infiernito" caught the attention of Disa Records, who the band would later sign onto. The band released their debut studio album, Renovar o Morir, in 2010, which peaked at number 20 on the Billboard Top Latin Albums chart.

2011–2012: De Sinaloa Para el Mundo and El Buen Ejemplo
On January 1, 2011, the band released their second studio album, De Sinaloa Para Todo el Mundo. The album spawned the single "El Tierno Se Fue", which peaked at number 15 on the Hot Latin Songs chart.
