Winona Grace MacInnis OC OBE (née Woodsworth; July 25, 1905 – July 10, 1991) was a socialist Canadian politician. She was the first woman from British Columbia elected to the House of Commons of Canada, as well as the first wife of a former Canadian Member of Parliament to be elected to the House of Commons in her own right, rather than by directly succeeding her husband in a by-election following his death. MacInnis represented the British Columbia riding of Vancouver—Kingsway. She was the only woman MP elected in the 1968 election.
