The Caisse de dépôt et placement du Québec is an institutional investor that manages several public and parapublic pension plans and insurance programs in the Canadian province of Quebec. It was established in 1965 by an act of the National Assembly, under the government of Jean Lesage, as part of the Quiet Revolution, a period of social and political change in Quebec. It is the second-largest pension fund in Canada, after the Canada Pension Plan Investment Board. It was created to manage the funds of the newly created Quebec Pension Plan, a public pension plan that aimed to provide financial security for Quebecers in retirement. The CDPQ’s mandate was to invest the funds prudently and profitably while also contributing to Quebec’s economic development. As of December 31, 2023, CDPQ managed assets of C$434 billion, invested in Canada and elsewhere. CDPQ is headquartered in Quebec City at the Price building and has its main business office in Montreal at the Édifice Jacques-Parizeau.

An institutional investor is an entity that pools money to purchase securities, real property, and other investment assets or originate loans. Institutional investors include commercial banks, central banks, credit unions, government-linked companies, insurers, pension funds, sovereign wealth funds, charities, hedge funds, real estate investment trusts, investment advisors, endowments, and mutual funds. Operating companies which invest excess capital in these types of assets may also be included in the term. Activist institutional investors may also influence corporate governance by exercising voting rights in their investments. In 2019, the world's top 500 asset managers collectively managed $104.4 trillion in Assets under Management (AuM).
