An laparoscopic specimen retrieval shoehorn ("LSRS") is described. The LSRS has a primary shaft with a rearward portion, an intermediate portion, and a forward portion. The forward portion is radially-enlarged relative to the intermediate portion. A secondary shaft is slidably disposed within the primary shaft. The secondary shaft has an endo-bag attached thereto. A sheath having expanded and contracted positions is slidably disposed around the primary shaft. The sheath has a holding ring disposed radially-outwardly from the intermediate portion of the primary shaft. The holding ring is adapted to slide relative to the intermediate portion. The holding ring is disposed at a rear end of the sheath. A plurality of circumferentially-spaced prongs are disposed at a forward end of the sheath. During transition from the contracted to the expanded position of the sheath, the radially-enlarged forward portion expands the prongs radially-outwardly.
