The Worshipful Company of Blacksmiths is one of the ancient livery company of the City of London. With origins dating back to 1299, the company regulated many aspects of smithing within the City and its immediate environs, including who was allowed to practise the trade, their hours of work and the quality of their goods and workmanship.

To this day, the company supports the blacksmithing community across the country, awarding prizes for high-quality work and sponsoring young practitioners.
