Family Tree is a box set of musical material by Icelandic singer Björk.

This compact disc features songs by her previous bands: Kukl, the Elgar Sisters, and the Sugarcubes.

Roots CD 2 features B-sides and alternate versions of album tracks; Beats, which focuses on both new and old songs with a heavier electronica influence; and finally Strings CDs 1 and 2, which feature live and studio recordings of Björk with the Brodsky Quartet through 1999 and 2000.

The artwork on the CD was designed by M/M Paris in collaboration with Icelandic contemporary artist Gabríela Friðriksdóttir.

Björk's notes for the project, as featured on the individual CD artworks, reveal that "Immature" and "My Spine" were initially considered to feature on the compilation, as well as track(s) recorded with British composer John Tavener.
