Andreas of Bergamo (Latin: Andreas Bergomas or Bergomatis) was an Italian historian of the late ninth century. He composed a continuation of the Historia Langobardorum of Paul the Deacon in 877. The short continuation, sometimes called the Andreæ presbyteri Bergomatis chronicon, continues Paul's history up until the late 870s. It is an important primary source for the Italy, and especially the Lombardy, of its time and is the best source for the succession dispute following the death of the Emperor Louis II.
Andreas saw himself as both a Lombard and a Frank and he therefore naturally tells the story of the Carolingians in his "historia Langobardorum". Andreas saw the Carolingian Empire as a unity.
