Theodore Gardelle (November 30, 1722 - April 4, 1761) was a Swiss limner and enameller.
He was born in Geneva, where he studied miniature painting. Having acquired its first rudiments, he went to Paris in 1744. There he gained great proficiency in the art. He lived there studying and painting until 1750. Then he returned to his native place and practised his profession for some years. In 1756, he again went to Paris. In 1760, he went to England, where he was executed in the Haymarket, London, for murdering his landlady.
