A bolas (plural: bolas or bolases; from Spanish bola, "ball", also known as boleadoras) is a type of throwing weapon made of weights on the ends of interconnected cords, used to capture animals by entangling their legs. Bolas were most famously used by the gauchos (Argentinian cowboys), but have been found in excavations of Pre-Columbian settlements, especially in Patagonia, where indigenous peoples (particularly the Tehuelche) used them to catch 200-pound guanaco (llama-like mammals) and ñandú (birds). The Mapuche and the Inca army used them in battle. Researchers have also found bolas in North America at the Calico Early Man Site.

Gauchos use boleadoras to capture running cattle or game. Depending on the exact design, the thrower grasps the boleadora by one of the weights or by the nexus of the cords. He gives the balls momentum by swinging them and then releases the boleadora. The weapon is usually used to entangle the animal's legs, but when thrown with enough force might even inflict damage (i.e., breaking a bone).

Traditionally, Inuit have used bolas to hunt birds, fouling the birds in air with the lines of the bola. People of a Feather showed Belcher Island Inuit using bolas to hunt eider ducks on the wing.

There is no uniform design; most bolas have two or three balls, but there are versions of up to eight or nine. Some bolas have balls of equal weight, others vary the knot and cord. Gauchos use bolas made of braided leather cords with wooden balls or small leather sacks full of stones at the ends of the cords.
