Peter Alexander Hoy (born June 29, 1966) is a Canadian former relief pitcher in Major League Baseball who played briefly for the Boston Red Sox during the 1992 season.

Listed at 6 feet 7 inches (2.01 m), 220 pounds (100 kg), Hoy batted and threw right-handed.

Hoy made Boston's roster out of spring training in 1992 largely on the strength of his sinker but, in the words of the Regina Leader-Post's John Chaput, "just when he reached The Show ... his sinker disappeared."

He made five relief appearances in six weeks on the Major League roster and posted a 7.36 earned run average in 3⅔ innings of work.
