Charlie Brown Jr. (also simply known as Charlie Brown and sometimes abbreviated as CBJr.) was a two-time Latin Grammy Award-winning Brazilian alternative rock band from Santos, São Paulo. Known for their lyrics laden with social criticism and skate punk/hip hop jargon appealing to marginalized youth, they were one of the most famous Brazilian acts of the late 1990s/early to mid-2000s; their success, though, was frequently overshadowed by controversies and clashes regarding vocalist (and only founding member to remain consistently in all of the group's line-ups) Chorão and his bandmates, his feuds with other musicians (more famously with Marcelo Camelo of Los Hermanos), and his struggle with drug abuse. According to a survey made by streaming platform Deezer in 2015, Charlie Brown Jr. was the second most-listened Brazilian band outside Brazil, losing only to Sepultura; in another survey by Spotify, also from 2015, they were placed 31st out of 47 bands and artists.
Following Chorão's death due to a cocaine overdose on March 6, 2013, the band ceased its activities and its remaining members regrouped as A Banca in April, intending to continue performing as a "tribute act/spiritual successor" to Charlie Brown Jr.; however, A Banca only lasted for five months as their frontman, Champignon, committed suicide on September 9.
In 2019, garnering much controversy and negative reception from long-time fans and acquaintances of Chorão, Marcão, Heitor Gomes and André Pinguim reunited Charlie Brown Jr. for a series of shows with guest vocalists held throughout the year. They were reunited once again in 2021 for the "Chorão 50 Tour", a special tour around Brazil commemorating Chorão's 50th birthday.
