Terry Duguid is a politician in Manitoba, Canada. He has campaigned for elected office at the municipal, provincial and federal levels, but has only achieved success in the first of these. He is the son of two time World and Canadian curling champion Don Duguid .

Duguid holds a Bachelor of Science degree in Biology and a Master's Degree in Environmental Science. He has been involved a variety of eco-business pursuits in the Winnipeg area, managing the Sustainable Development International for a time, and serving as Chairman of the Manitoba Clean Environment Commission. He is currently President and CEO of the Gateway North Marketing Agency, which is responsible for ensuring the survival of the Hudson Bay Rail Line. He is also the founding president of the International Centre for Infectious Disease Control.

Duguid served as a Winnipeg city councillor from 1989 to 1995, and was on a number of government committees during this period. He ran for Mayor of Winnipeg in 1995, placing third, behind Susan Thompson who was re-elected and Peter Kaufman who placed second.

Duguid also campaigned for the Manitoba legislature in the 1990 provincial election, as a Liberal in the north-Winnipeg riding of Rossmere. He received 2416 votes, finishing behind both his Progressive Conservative and New Democratic opponents.

In the Canadian federal election of 2004, Duguid was the Liberal candidate in the north Winnipeg riding of Kildonan—St. Paul, a riding previously held by Liberal MP Rey Pagtakhan (who chose to run in a different riding). Duguid's nomination process was controversial, in that it was delayed by the national party on more than one occasion. Some have suggested that the Liberal Party wanted to ensure that the seat would be open for Glen Murray, if he chose to run; Murray eventually decided to campaign in a different riding (Charleswood—St. James ), and Duguid's nomination was allowed to stand.

The divisive nomination process may have contributed to Duguid's narrow loss (13582 votes to 13304) to Conservative candidate Joy Smith, who had several more months to campaign. Duguid's past support for toll roads on Winnipeg's outskirts may have also alienated some suburban voters.
