The present invention relates to a battery module and a battery pack including same. A battery module according to an embodiment of the present invention comprises: a battery cell lamination in which a plurality of battery cells are stacked; a module frame for accommodating the battery cell lamination; a heat sink formed at a floor part of the module frame; and a cooling port for supplying a refrigerant to the heat sink. The module frame includes a module frame protrusion formed by protrusion of a portion of the floor part of the module frame. The module frame protrusion includes a first module frame protrusion and a second module frame protrusion which are positioned at one side of the module frame and spaced apart from each other. The cooling port includes a refrigerant injection port and a refrigerant discharge port. The refrigerant injection port and the refrigerant discharge port are arranged on the first module frame protrusion and the second module frame protrusion, respectively.
