Wilf Hanni (born February 19, 1948) is a Canadian politician and oil industry consultant in British Columbia.

At the Reform Party's August 30, 1997 leadership convention in Surrey, Hanni was elected leader over John Motiuk and Adrian Wade.

He ran in the October 29, 2008 Vancouver-Fairview by-election, receiving 483 votes (4.11% of total ballots cast in the riding).

He resigned as leader in June 2009 along with eight members of the party's board of directors, saying that he "spent much of the last four years fighting a long and protracted battle with a group of dissidents.

The new party advocated creating a provincial constitution, replacing the existing first-past-the-post voting system with preferential voting, and replacing taxation system with a single rate income tax or a single rate consumption tax (decided in a referendum).
