The Corconti or Korkontoi were an ancient people, named as Germanic, in (2.10) of the Geography of Ptolemy (after 83 – 161 AD). They resided in the vicinity of Asciburgius Mountain somewhere near the sources of the Vistula. Asciburgius was on the edge of the Giant Mountains range (Krkonoše in Czech, Karkonosze in Polish, Riesengebirge in German).
The tribe may have been named after the terrain but their identity is uncertain. Ptolemy counted them among the Germani on grounds of their inhabiting Magna Germania. They may have been part of the Marcomanni, who lived in the region. Quadi were also present in the area. Alternatively, the Corconti may have belonged to earlier tribes; residents of mountains are often hold-outs from an earlier culture. The etymology of the name is uncertain. No accepted derivation has been found in Germanic, Slavic or Celtic. If not Indo-European, it may be Pre-Indo-European in origin.
