André Ouellet (born April 6, 1939) is the former President of Canada Post and had previously been a long time Liberal politician.

First elected to in 1967, Ouellet served in a number of different positions in the cabinets of Lester B. Pearson and Pierre Trudeau. Ouellet represented the safe Liberal seat of Papineau in Montreal for almost thirty years and even when the Liberals were crushed by the Tories in the election of 1984 he retained his seat by a substantial margin. In opposition Ouellet became the Liberal's leading figure in the constitutional negotiations that led to the Charlottetown Accord, and was a strong advocate for the constitution, which was rejected in the 1992 referendum.

With the return to power of the Liberals after the 1993 Canadian election Ouellet became a senior minister being made Minister of Foreign Affairs by new PM Jean Chrétien. Despite his experience Oullet was not popular in Quebec, and the lasting legacy of the Charlottetown Accord hurt him. After the close result of the 1995 Quebec referendum Chrétien promised to bring new blood into the Quebec Liberal party. In 1996 Chrétien thus appointed Oullet to head Canada Post Corporation, his seat in the Canadian House of Commons was taken by Pierre Pettigrew in a by-election later that year.

Oullet was a former Canadian Postmaster General and had done much to reform the Post Office leading to record profits by the agency. Recently controversy has surrounded Oullet as the post office is one of the organizations embroiled in the Sponsorship Scandal. As a result Ouellet was suspended from his position at Canada Post in February 2004 by new PM Paul Martin. He resigned as president of Canada Post on August 12 2004, further revealing Oullet's role in awarding untendered contracts and his failure to provide invoices for hundreds of thousands of dollars of personal expenses.
