Lisa Redfield Peattie (1924–2018) was an American anthropologist and professor of urban anthropology at the Massachusetts Institute of Technology. She was best known for her work in advocacy planning, a type of urban planning which seeks social change by including all interests and groups in the planning process. Peattie, who earned her Ph.D. from University of Chicago in 1968, published extensively on slums and squatter settlements. She also engaged in numerous peace actions, and had a long, although minor and nonviolent, arrest record.
