Repoussé or repoussage [ʁəpusaʒ] refer to a metalworking technique in which a malleable metal is shaped by hammering from the reverse side to create a design in low relief. Chasing, chased work, or embossing refer to a similar technique, in which the piece is hammered on the front side, sinking the metal. The two techniques are often used in conjunction.

Many metals can be used for chasing and repoussé work, including gold, silver, copper, and alloys such as steel, bronze, and pewter.
