Vähilaadsed (Crustacea) ehk koorikloomad on lülijalgsete loomade alamhõimkond, kes ilmusid esmakordselt Kambriumi ajastul ning kes on mitmekesiselt esindatud ka tänapäeva veelistes keskkondades. Iseloomulikeks tunnusteks vähiaadsete puhul on lüliline ja kõva koorikuga kaetud keha, hingamiseelunditena toimivad lõpused, kaks paari tundlaid, pea peale või tundlate otsa kinnituvad silmad. Selle alamhõimkonna tüüpilisemateks näideteks on hästi relvastatud krabid ja lobsterid. Suurt geoloogilist väärtust omavad aga vähilaadsete hulka kuuluvad ostrakoodid ja nuivähid.
