Paul Marny was a British–French artist.

Marny was born in Paris; his real name may have been Paul François or Charles Paul Goddard. He worked in the theatre, and as a porcelain decorator for the Sèvres factory, before moving to Belfast to work with a French architect. In 1860 he moved to Scarborough, at the suggestion of Oliver Sarony, the photographic pioneer and brother of Napoleon Sarony. There he taught Albert Strange and other Scarborough artists. William Tindall was his brother-in-law.

Marny exhibited at the Royal Academy. In 1874 the British Journal of Photography reported that

'A Gallic brother, M. Paul Marny Godard, of Paris, has obtained a patent for the application of carbon printing to porcelain or other similar substance, which, after the picture is developed, receives a coating of transparent enamel ...".

He died in Scarborough, North Yorkshire, on 24 October 1914.
