Louder Than Love is the second studio album and major-label debut by American rock band Soundgarden. It was released on September 5, 1989, by A&M Records. After touring in support of their debut album, Ultramega OK (1988), Soundgarden left SST, signed with A&M and began work on its first album for a major label. The songs on the album featured a metal-leaning grunge sound with some songs featuring unusual or unorthodox time signatures.

Due to the nature of some of the lyrics (particularly "Big Dumb Sex"), a Parental Advisory sticker was placed on the album packaging. Louder Than Love would become the band's first album to chart on the Billboard 200, peaking at No. 108. The band supported the album with tours of North America and Europe. It was the last Soundgarden album to feature the band's original bassist, Hiro Yamamoto. It was later reissued on January 25, 2002.
