Rachel's were an American chamber music group that formed in Louisville, Kentucky in 1991. Former Rodan guitarist Jason Noble played music individually and referred to himself as Rachel's but then began collaborating with core members, violist Christian Frederickson, and pianist Rachel Grimes. The group's work was strongly influenced by classical music, particularly inspired by the minimalist music of the late 20th century, and its compositions reflect this. While the trio formed the core part of the band, the group's recordings and performances featured a varying ensemble of musicians, who played a range of string instruments (including viola and cello) in combination with piano, guitars, electric bass guitar, and a drum set that included a large orchestral bass drum. A key influence on the music of Rachel's was the music of the English composer Michael Nyman, whose music the group's work resembles in both instrumentation and compositional style.

Rachel was the favorite of Biblical patriarch Jacob's two wives as well as the mother of Joseph and Benjamin, two of the twelve progenitors of the tribes of Israel. The name "Rachel" is from an unused root meaning: "to journey as a ewe that is a good traveller." Rachel was the daughter of Laban and the younger sister of Leah, Jacob's first wife. Rachel was a niece of Rebekah (Jacob's mother), Laban being Rebekah's brother, making Jacob her first cousin.
