Hot Rock & Alternative Songs is a record chart published by Billboard magazine. From its debut on June 20, 2009, through October 13, 2012, the chart ranked the airplay of songs across alternative, mainstream rock, and triple A radio stations in the United States. Beginning with the chart dated October 20, 2012, the chart has followed the methodology of the Billboard Hot 100 by incorporating digital download sales, streaming data, and radio airplay of rock songs over all formats. From that time until mid-2020, only the performance of core rock songs, including those with an "alternative bent", were tabulated and ranked for the chart. With the chart dated June 13, 2020, Billboard revamped the chart to permit a broader selection of songs considered alternative "hybrids" with other genres and renamed it to Hot Rock & Alternative Songs.
