Margo Lewers (1908–1978) was an Australian interdisciplinary abstract artist who worked across the media of painting, sculpture, tapestry, ceramics and the domestic arts. She was renowned for a number of major public commissions and for her landscaping and interior design for the family home at Emu Plains. Her early compositions explored colour and formal geometric abstraction; her work became more fluid and expressionist by the early 1960s. She showed extensively in Australia and in several international travelling exhibitions. She won at least fourteen awards and prizes. The Penrith Regional Gallery and Lewers Bequest now stands on her property at Emu Plains.
