Cire Trudon is a French candlemaker and the oldest wax-producing factory worldwide. Founded in 1643, it was the provider of the royal court of Louis XIV, as well as most of the great churches of France.

Cire Trudon was the biggest wax-producing factory in the French Kingdom during the 17th and 18th centuries. In 1762, in his encyclopaedia The art of the wax producer, engineer Duhamel du Monceau, praises the skills of the Trudons and gives the manufacture as an example.

Such a level of quality led to King Louis XIV elevating Charles Trudon to the French nobility as Count Trudon des Ormes.

Cire Trudon still keep records of recipe and tools of wax whitening: wrought iron, 17th century pans. The moulds used to form candles bearing the royal blazons still remain ("Easter candle church for the Royal Chapel in Versailles, night candle for the King…").
