Mercer is an English occupational surname for a trader or dealer in textiles, especially costly fabrics like silk, velvet, and fine wool. The name traces its origins to the Old French mercier, which itself derives from the Latin merx, meaning "merchandise" or "goods." In medieval England, mercers formed a prominent guild, the Worshipful Company of Mercers, one of the Great Twelve Livery Companies of London, which played a significant role in the cloth trade. In French, the name took the form Mercier, reflecting the same occupation across the Channel. Notable Bearers Mercer has been adopted as a given name as well as a surname.
