The Askew Codex (a.k.a. Codex Askewianus) is a parchment manuscript now held by the British Library (BL Additional MS 5114) which contains Coptic translations of the Gnostic Pistis Sophia and parts of what G. R. S. Mead referred to as "extracts from The Books of the Savior." It was purchased by the British Museum (now British Library) in 1795 from Dr. Anthony Askew. Until the discovery of the Nag Hammadi library in 1945, the Askew Codex was one of three surviving codices contained all of the gnostic writings that had survived until recent times; the other two being the Bruce Codex and the Berlin Codex.
