John Mazza (born February 23, 1964) is a left-handed ten-pin bowler and former touring player for the Professional Bowlers Association (PBA). Mazza won eight titles on the PBA Tour and collected over $850,000 in earnings. He also won 11 PBA Regional titles.
Mazza became a PBA member in 1982, joining the full-time PBA Tour in the late 1980s. He finally hit his stride in 1991. That season, he won three PBA titles and the Harry Smith PBA Points Leader award, while cashing nearly $150,000 in earnings. Mazza is most notable, however, for being the second player (and first left-hander) to convert the nearly-impossible 7-10 split on national television. Mark Roth was the first to make this split on TV, and Jess Stayrook accomplished the feat shortly after Mazza.
In some ABC-TV Professional Bowlers Tour broadcasts during the early- to mid-1990s, Mazza served as a lane-level reporter.
