The Codex Faenza (Faenza, Biblioteca Comunale 117) abbreviated as "(I-FZc 117)", and sometimes known as Codex Bonadies, is a late 15th-century musical manuscript containing some of the oldest preserved keyboard music along with additional vocal pieces. The manuscript is still held at the Biblioteca Comunale di Faenza, near Ravenna, but facsimiles are held in other libraries in Italy and overseas.
