Tintamarre is an Acadian tradition of marching through one's community making noise with improvised instruments and other noisemakers, usually in celebration of National Acadian Day. The term originates from the Acadian French word meaning "clangour" or "din". The practice is intended to demonstrate the vitality and solidarity of Acadian society, and to remind others of the presence of Acadians. It originated in the mid-twentieth century, likely inspired by an ancient French folk custom.
