The Woodbine Mile is a Grade I stakes race on turf for Thoroughbred racehorses three years old and up held annually in mid September at Woodbine Racetrack in Toronto, Canada. Currently sponsored by Bell Canada, the Woodbine Mile carries a purse of $1 million and is a qualifying race for the Breeders' Cup Turf Mile. Part of the Breeders' Cup Challenge series, the winner of the 2008 Woodbine Mile automatically qualifies for the Breeders' Cup Mile.

The inaugural race in 1988 was sponsored by Molson Breweries with a purse of $750,000 and run as the Molson Export Challenge, reflecting the name of the company's flagship beer. It was changed to the Molson Export Million when the purse was increased to $1 million. In 1999, under new sponsorship it was renamed and raced as the Atto Mile until 2006. Since inception, the race has been run at three different distances. Originally restricted to three-year-olds, with the modification to one mile in 1997 the race was also made open to older horses.
