Portrait of Lady Manners is a 1794 portrait painting by the British artist Thomas Lawrence. It features a full-length view of the Irish author Catherine Gray, Lady Manners. The County Cork-raised Gray was known for her poetry. She married the Tory politician Sir William Manners and her son later became Earl of Dysart. She is shown at the bottom of a some marble steps holding a rose with a peacock behind her. Although Romantic in style, Lawrence made references to neoclassical themes. Her pose is taken from the Medici Venus while the peacock is likely an allusion to Juno. The Borghese Vase is seen in the rop right.
