Peter Luke Smith (born March 19, 1940) is a former pitcher in Major League Baseball who played from 1962 to 1963 for the Boston Red Sox. Listed at 6' 2", 190 lb., Smith batted and threw right-handed. A native of Natick, Massachusetts, he attended Colgate University.
In a two-season career, Smith posted a 0–1 record with a 6.75 ERA in seven appearances, including two starts, giving up 14 runs on 18 hits and eight walks while striking out seven in 18+2⁄3 innings of work.
- On September 28, 1963, at Fenway Park, Smith started a triple play against the Angels with the last ball he fielded in the majors. With Charlie Dees running on second base and Lee Thomas on first, Félix Torres tried to advance both runners with a bunt. Unfortunately for Torres, Smith fielded cleanly the ball and threw to 3B Frank Malzone, who tagged Dees out before throwing the ball to SS Eddie Bressoud, covering second to double out Thomas. Bressoud then threw to 2B Félix Mantilla, who covered first and completed the 1-5-6-4 triple play.
