Haim ( HY-im; meaning "life" in Hebrew, stylized HAIM) is an American rock band, based in Los Angeles and comprising three sisters, Este (bass guitar and vocals), Danielle (lead vocals, guitar, and drums), and Alana Haim (guitars, keyboards, and vocals). In addition to their primary instruments, each is proficient in several others. The group's pop sound on their studio work stands in contrast to the more rock-oriented sound of their live shows.

The sisters grew up in a musical family, and began playing instruments from an early age in the cover band Rockinhaim, fronted by their parents, Moti and Donna. The two elder sisters, Este and Danielle, performed briefly with the pop group Valli Girls in 2005, releasing a few songs on soundtrack and compilation albums under that name. In 2007, they formed Haim with younger sister Alana, but did not seriously consider it a professional career for some years. After Danielle became a successful touring guitarist, first with Jenny Lewis and later with Julian Casablancas, Haim reformed as a full-time operation in 2012.
