Lady Lilith is an oil painting by Dante Gabriel Rossetti first painted in 1866–1868 using his mistress Fanny Cornforth as the model, then altered in 1872–73 to show the face of Alexa Wilding. The subject is Lilith, who was, according to ancient Judaic myth, "the first wife of Adam" and is associated with the seduction of men and the murder of children. She is shown as a "powerful and evil temptress" and as "an iconic, Amazon-like female with long, flowing hair."

Gabriel Charles Dante Rossetti, generally known as Dante Gabriel Rossetti, was an English poet, illustrator, painter, translator, and member of the Rossetti family. He founded the Pre-Raphaelite Brotherhood in 1848 with William Holman Hunt and John Everett Millais. Rossetti inspired the next generation of artists and writers, William Morris and Edward Burne-Jones in particular. His work also influenced the European Symbolists and was a major precursor of the Aesthetic movement.
