The Toronto Maple Leafs Minor League Baseball team played from 1896 to 1967 in Toronto, Canada, as members of the International League (IL). In their 71-year history, the team's pitchers threw 17 no-hitters, tying them with the original Buffalo Bisons for the second-most in the IL behind the Rochester Red Wings, who have 20 no-hitters. A no-hit game occurs when a pitcher (or pitchers) allows no hits over the course of a game.^[1] A perfect game, a much rarer feat, occurs when no batters reach base by a hit or any other means, such as a walk, hit by pitch, or error.^[1]

Among the 16 pitchers who accomplished Toronto's 17 no-hitters, Augie Prudhomme stands out as the only Maple Leafs hurler to achieve this feat twice, once in 1927 and again in 1928. Dave Vineyard recorded two no-hitters for International League teams, one with the Maple Leafs in 1967 and one previously with the Red Wings in 1966. The Maple Leafs also surrendered 11 no-hitters throughout their history, including a perfect game pitched by Bill Harris in 1936.

Nine of Toronto's no-hitters occurred while the International League competed at the Double-A classification, and eight while at Triple-A, though each level was the highest level of the minors at the time. Three were pitched at the Leafs' first home ballpark, Hanlan's Point Stadium, where the team played from 1897 to 1900 and again from 1908 until 1925. Eleven were pitched at Maple Leaf Stadium, where they played from 1926 until their disbandment in 1967. Three were pitched in road games.
