Jean-Louis Nicolas Jaley (27 January 1802, Paris - 30 May 1866, Neuilly-sur-Seine) was a French sculptor.
He was the pupil of his father Louis Jaley and Pierre Cartellier. In 1827, he won - together with François Lanno - the Prix de Rome for sculpture with a bas-relief Mucius Scævola devant Porsenna.
He was buried in the Père Lachaise Cemetery (49th division), near his father, who died in 1840.
