Peter Leo Van Loan, PC, KC (born April 18, 1963) is a former Canadian politician who served as the Member of Parliament for the electoral district of York—Simcoe from 2004 to 2018.

Van Loan was a key figure in the unsuccessful attempt to convince Premier of New Brunswick Bernard Lord to run for the leadership of the federal Progressive Conservatives in late 2002.

On October 30, 2008, Jay Hill replaced Van Loan as Government House Leader and Steven John Fletcher took over the Minister for Democratic Reform post.

On these changes Don Martin wrote: "The House of Commons might become a slightly friendlier place now that Peter Van Loan has lost the job of Question Period cheap shot specialist to become Public Safety Minister, a good move that seems to back Harper’s pledge to play nice with others during the upcoming session.

[2] Van Loan was one of thirteen Canadians banned from travelling to Russia under retaliatory sanctions imposed by Russian President Vladimir Putin in March 2014.
