The Briançonnais microcontinent or Briançonnais terrane is a piece of continental crust found in the Penninic nappes of the Alps.
According to some paleogeographic reconstructions the Briançonnais microcontinent was in fact a part of the microcontinent Iberia, that encompassed not only the Iberian Peninsula but also Corsica, Sardinia and the Balearic Islands. Because paleogeographic reconstructions of highly deformed pieces of crust are always difficult, this is disputed among geologists.
The Briançonnais microcontinent is named after the French city of Briançon.
