Corneille de Lyon (died 1574)

Dutch-born French painter. He became a naturalized French subject in 1547 and was court painter to Henry II and Charles IX, working in Lyon 1541–74. He is known to have painted small portraits, though no works are attributed to him with certainty.

A number of paintings, distinguishable from those of his contemporary François Clouet (and, unlike them, apparently not based on preliminary drawings), are considered as being in his style.
