The Macdonald–Laurier Institute (MLI) is a public policy think tank located in Ottawa, Ontario, Canada.
Founded in 2010, the institute is named after John A. Macdonald, a Tory and Canada's first Prime Minister, and Wilfrid Laurier, a Liberal and the country's first French-Canadian Prime Minister. MLI is a registered charity and is funded by corporate and individual donors and private foundations.
MLI's analysis has been described as market-oriented. It is affiliated with the Atlas Network, a conservative and libertarian group based in the United States. MLI describes itself as non-partisan, a description used for it by The Economist in 2010 and The Globe and Mail in 2024. In August 2022, Russia designated the MLI as an "undesirable organisation".
