Wampum are traditional, sacred shell beads of Eastern Woodlands tribes. They include the white shell beads fashioned from the North Atlantic channeled whelk shell; and the white and purple beads made from the quahog, or Western North Atlantic hard-shelled clam.

Woven belts of wampum have been created to commemorate treaties or historical events, and for exchange in personal social transactions, such as marriages. In colonial North America, European colonists often used wampum as currency for trading with Native Americans.
