The present invention relates to a GRP78-derived peptide for screening highly efficient stem cells and the use thereof, and more particularly, to screening highly efficient stem cells using, as a marker, a GRP78-derived peptide capable of binding to the binding domain of GRP78 protein on the cell surface. According to the present invention, the GRP78-derived peptide comprising only a specific amino acid sequence capable of recognizing highly efficient stem cells, among the amino acid sequence of GRP78, makes it possible to screen only non-senescent young stem cells. In addition, when stem cells are treated with the GRP78-derived peptide or the GRP78-derived peptide is introduced into stem cells, the efficiency of the stem cells can be increased. Thus, the GRP78-derived peptide is useful for the production of stem cell therapy products having excellent efficacy.
