The Aachen Gospels (German: Schatzkammer-Evangeliar "Treasury Gospels", or Karolingisches Evangeliar "Carolingian Gospels") are a Carolingian illuminated manuscript which was created at the beginning of the ninth century by a member of the Ada School. The Evangeliary belongs to a manuscript group which is referred to as the Ada Group or Group of the Vienna Coronation Gospels. It is part of the church treasury of Charlemagne's Palatine Chapel, now Aachen Cathedral, and is today kept in the Aachen Cathedral Treasury. The Treasury Gospels and the more recent Ottonian Liuthar Gospels are the two most significant medieval manuscripts on display there.
