Adolphe Pierre Leleux (15 November 1812, in Paris – 27 July 1891) was a French painter and illustrator.
His brother Armand Leleux was also a painter.
Adolphe Leleux was self-taught, and exhibited work at the Paris Salon from 1835 onwards.
Although he decided to concentrate on painting after 1837, he did study engraving in the studio of Alexandre Vincent Sixdeniers.
He was given the nickname "Leleux le Breton".
