Tienpotiges (Decapoda) is 'n biologiese orde van geleedpotige diere. Krappe, krewe en garnale behoort aan die orde. Behalwe vir 'n paar uitsonderings, leef hierdie diere in die see.

Soos die naam aandui, het alle tienpotiges vyf paar looppote. Die looppote is die laaste vyf pare aanhangsels op die voorste helfte van die kopborsstuk (cephalothorax). Ten minste een paar dra knypers. Die agterlyf het dikwels vyf paar swempote, wat ook deur die wyfies gebruik word om hul eiers te dra. Sommige spesies het 'n stertvin. Krappe, daarteenoor, het 'n baie klein agterlyf, wat onder die karapaks (dop) gedra word, maar geen stert nie.

Baie tienpotiges is aasvreters - wat dooie plante en diere vreet. Krappe is omnivore, wat alge en skulpvis (soos weekdiere) vreet. Krewe vreet meestal lewendige prooi.
