Way Group (Spanish: Grupo Way) is a geologic group of Lower Cretaceous age located in northern Chile. The sediments of the group deposited in Coloso Basin, a small intra-arc basin made up by a half graben. The now inactive Coloso Basin is elongated along a NNW-SSE oriented axis and has its southwestern border made up by faults.^[1]

The Way Group is made up of the following arrangement from top to bottom the Tablado Formation made up chiefly of limestone, the conglomerate-gravel-sandstone Lombriz Formation and the conglomerate and breccia dominated Caleta Coloso Formation.^[2]
