The Mediæval Bæbes are an English ensemble of female musicians founded by Miranda Sex Garden member Katharine Blake in London in 1996, featuring some of her MSG cohorts as well as other friends who share her love of medieval music. The lineup often rotates from album to album, and ranges from 6to 12 members.

The Bæbes’s first album, Salva Nos (1997), shot straight to No 2 in the classical charts, a silver disc. Subsequent albums include Worldes Blysse (which went straight to No 1), Undrentide, (co-produced by John Cale), The Rose, and the Christmas-themed album Mistletoe & Wine.
