Peter Joseph Schneider (August 20, 1895 – June 1, 1957) was an American pitcher in Major League Baseball who played for the Cincinnati Reds (1914–1918) and New York Yankees (1919).

Born in Los Angeles, California, Schneider was a hard-throwing pitcher who struggled with injuries and control problems.

His most productive season came in 1917 when he posted career-highs with 20 wins and 333+2⁄3 innings pitched, but he lost 19 games for the third consecutive year.

On May 11, 1923, he set league records by hitting five home runs with 14 RBI in a game, during a 35–11 romp over Salt Lake City.

The two men apparently resolved their differences and left together when the fight resumed, whereupon Schnabel collapsed after being hit by Schneider, fracturing his skull, leading to his death.
