The AA. present and discuss the Late Cretaceous evolution of the Southeast France Basin (SEFB) owing the Pyrenean and Alpine belts. The available geological data (isopachs maps, boreholes and field data) were integrated in 3D GeoModeller software to build a 3D model of the Cenomanian to Campanian sedimentary series of the Late Cretaceous period. A significant eastward marine regression during the Late Cretaceous is revealed. According to the location of the Late Cretaceous depocenters, 2 sub-basins are recognized in the SEFB and correspond to "en-échelon" synclines filled by syn-buckling sediments. These events are related to the sub-meridian "Pyrenean-Provence" crustal shortening. During Campanian time, the deepening and the tilting of the SEFB are interpreted as a consequence of the subduction of the Alpine Tethys. The Late Cretaceous SEFB is the prolongation on the European foreland of the Alpine subduction trench
