Fanny Cornforth (3 January 1835 – 24 February 1909) was an Englishwoman who became the artist's model and mistress of the Pre-Raphaelite painter Dante Gabriel Rossetti.
Later, Cornforth performed the duties of housekeeper for Rossetti.
William Michael Rossetti, the artist's brother, wrote that "she was a pre-eminently fine woman with regular and sweet features, and a mass of the most lovely blond hair – light-golden, or 'harvest yellow'."In Rossetti's paintings, the figures modeled by Fanny Cornforth are generally rather voluptuous, differing from those of other models such as Jane Morris and Elizabeth Siddal.
