Bocas Ordinárias is the fifth album by Brazilian alternative rock band Charlie Brown Jr., released in December 2002 through EMI. Vocalist Chorão described it as a "sequel of sorts" to Abalando a Sua Fábrica, in which it continues the heavy aggressiveness of its predecessor, and dedicated it to his friend, fellow singer Cássia Eller, who died the year prior. The album's title comes from a Portuguese popular expression; saying someone has a "boca ordinária" means that they are foulmouthed. Chorão got acquainted with the expression after reading a negative critic from a Portuguese newspaper after the band performed in Portugal in 2002 as part of their international tour, and decided it would be the name of their next album.

Charlie Brown Jr. was a Brazilian rock band from Santos, São Paulo. The group was popular with disadvantaged youth because of their relatable commentary about social issues and the frequent use of skate punk and hip hop slang in their songs. The band won two Latin Grammy Awards and was one of the most-popular Brazilian bands of the late 1990s to mid-2000s.
