Kate Elizabeth Lechmere (13 October 1887 – February 1976) was a British painter who with Wyndham Lewis was the co-founder of the Rebel Art Centre in 1914. As far as is known, none of Lechmere's paintings have survived. She served as a nurse in England during the First World War and had a three year relationship with the poet and critic T.E. Hulme before he was killed. After the war she became a successful milliner.
