Lady Mary Georgina Filmer (née Cecil, 4 April 1838 - 17 March 1903) was an early proponent of the art of photographic collage.

A Victorian socialite, Lady Filmer produced several albums consisting of watercolour scenes decorated with photomontages. One of her works (from the so-called Filmer Album) depicts a drawing room, painted in watercolour, in which she has added photographic cut-outs from albumen silver prints.
