The Canada Pension Plan Investment Board (CPPIB; French: Office d'investissement du régime de pensions du Canada), operating as CPP Investments (French: Investissements RPC), is a Canadian Crown corporation established by way of the 1997 Canada Pension Plan Investment Board Act to oversee and invest the funds contributed to and held by the Canada Pension Plan (CPP).

CPP Investments is one of the world's largest investors in private equity, having invested over US$28.1 billion between 2010 and 2014 alone. Despite being a Crown corporation, CPPIB is not considered a sovereign wealth fund because it operates at arm's length from the Government of Canada and solely manages CPP contributions paid by workers and employers, not public funds.

As of September 30, 2025, the CPP Investment Board manages over C$777 billion in assets under management for the Canada Pension Plan on behalf of 22 million Canadians. Canadians contributed $15.9 billion to the fund from individual payroll deductions in fiscal 2024.

CPP Investments is one of Canada's top eight pension funds, nicknamed the "Maple 8" or "Maple Revolutionaries."

The Canada Pension Plan was established in 1966. For much of its history, the plan relied on contributions to pay benefits. By 1996, the federal government had determined that the CPP as then constituted was unsustainable. Changes were made to the plan, gradually increasing the contribution rate to its current 9.9% and creating the CPP Investment Board.

Under the direction of then Minister of Finance Paul Martin, the CPP Investment Board was created by an Act of Parliament in 1997 as an independent, but accountable, body to monitor the funds held by the Canada Pension Plan. The CPP Investment Board began its investing program in 1999, establishing the CPP Reserve Fund to hold investment earnings and CPP contributions not needed to pay current pensions. It reports quarterly to the public on its performance, has a professional board of directors to oversee the operations of the CPP reserve fund, and also to plan changes in direction. As a Crown corporation, the CPP Investment Board is accountable to Parliament and reports annually through the Minister of Finance. While accountable to Parliament, the CPP Investment Board is not controlled by the government or subject to government appointments, its employees and directors are not part of the Public Service of Canada. CPPIB is a partner of the World Economic Forum.

The CPP Investment Board's mandate is laid out in its founding legislation, the Canada Pension Plan Investment Board Act (S.C. 1997, c. 40). Its sole investing mandate is to achieve a "maximum rate of return, without undue risk of loss".

The CPP Investment Board invests in private equity, public companies, and both residential and commercial real estate in major cities around the world. It also invests in real estate equities and real estate investment trusts (REITs). CPPIB made its first direct office investment in Seattle in 2016. Notable investments include 50% of the American pet store chain Petco, 50% of American luxury department store chain Neiman Marcus, 50% of Australian office tower development International Towers Sydney, 50.01% of the Ontario Highway 407 toll highway, 21.5% of South Korean discount store chain Homeplus, and 19.8% of multinational media corporation Entertainment One. Other prominent investments are made in Indian companies Byju's, Delhivery, Embassy Office Parks, Eruditus, Power Grid Corporation of India, SBI Life Insurance Company etc.
