The Billboard Brasil Hot 100 is a record chart in Brazil for songs, published weekly by Billboard Brasil magazine. First issued as Brasil Hot 100 Airplay in October 2009, the chart was initially published monthly and measured the airplay of songs on radio stations in the territory, as compiled by Crowley Broadcast Analysis. The first number-one song was "Halo" by Beyoncé. In 2014, the chart began to be published weekly. The magazine published the last issue of the Brasil Hot 100 Airplay on the chart dated 28 January 2019; Crowley continued publishing the chart as Top 100 Brasil on its own website. Subsequently, the magazine ceased operations for undisclosed reasons.
