Andreas von Barby (24 July 1508 - 3 August 1559) was a German-born nobleman in Danish service who served as "German Chancellor" (de facto Foreign Minister) under Christian III.
He was in this connection granted St. Lawrence's Chapel and the Provostry of Roskilde as fiefs in addition to an annual salary of 40 guilders.
In the verdict over Peder Oxe from June 1558 as well as at Christian III's funeral (by Jacob Bording), Barby is referred to as "German Chancellor" (de facto Foreign Minister) but it is unclear if he was ever officially appointed as such.
[2] In the later 1550s, Barby seems to have maintained a close relationship with the circle around Johann Friis and Peder Oxe.
He was involved in a bitter boundary dispute with Herluf Trolle and ended up selling the estate for 17,000 daler to Peder Oxe.
