"Black Rain" is a single by the American rock band Soundgarden, featuring lyrics written by frontman Chris Cornell and music written by bassist Ben Shepherd and guitarist Kim Thayil. The single debuted at number 24 and number 14 on the US Billboard Alternative Songs chart and the US Billboard Rock Songs chart respectively in August 2010. It is also Soundgarden's first and currently only song to chart on the Billboard Hot 100, peaking at #96. The song appears on the compilation album Telephantasm and on the music video game Guitar Hero: Warriors of Rock. This is the first single that Soundgarden has released since 1997.

The song was mostly recorded during sessions for Badmotorfinger in 1991. In 2010, the band reworked the original recording with Down on the Upside co-producer Adam Kasper, who was working with the band on archival material. Cornell noted that when they listened to the original recording for the first time after almost two decades, he immediately remembered the problems he had with the song. Cornell explained that the original version of the song was much longer, and that he was unhappy with how it was arranged. He was also dissatisfied with the lyrics in the chorus. After so many years, however, Cornell noted that the issues seemed "easy to resolve". For the new mix, the music was re-arranged, the chorus vocals were re-written and re-recorded by Cornell, and new guitar overdubs were added. Kim Thayil explained to Rolling Stone, "[In] many ways, it's a new song."

The verse is notable for being in the time signature 9/8. In an interview with USA Today, Cornell noted that "Black Rain" captures "that super heavy version (of the band) we were finally realizing to its fullest potential about 1991."
