Linda Francis Duncan (born June 25, 1949) is a Canadian lawyer and former politician who served as the member of Parliament (MP) for the riding of Edmonton Strathcona from 2008 until 2019.

She also spent time in Whitehorse working as an assistant deputy in the Yukon government, later consulting with Kluane First Nation and later in Montreal as Head Law and Enforcement for the NAFTA's Commission for Environmental Cooperation.

After a year in Ottawa, she moved to Whitehorse, where she worked as the assistant deputy Minister for Renewable Resources in the Yukon government.

She moved to Montreal after she accepted a position helping lead the enforcement department of the Commission for Environmental Cooperation of the North American Free Trade Agreement.

Acting as their vice-president during the August 2005 CN Rail oil spill, she was interviewed in the media on behalf of the land owners and lake users.

[4][5] Nevertheless, incumbent Conservative MP Rahim Jaffer, who had served since 1997, won his fourth mandate to represent the riding, with Duncan coming almost 5,000 votes behind him in second place.

[7] Duncan made support for public health care, enforcement of environmental laws, and driving the economy with 'green jobs' priorities in her campaign.

[15] Following a few days of silence and after his fiancée, fellow Conservative Member of Parliament Helena Guergis, flew to Edmonton and quietly married him, Jaffer conceded defeat to Duncan.

[16] With a 463-vote margin, Duncan became the only non-Conservative MP in Alberta, and the first NDP member from the province since Ross Harvey was elected at Edmonton East in 1988.

[18][19] When Parliament resumed in January 2009, Duncan sat as a member of the House Standing Committee on Environment and Sustainable Development.

Duncan had been suggested as a potential candidate in the leadership election, but she ruled herself out of running in September 2011[27] and later endorsed Paul Dewar.
