Raymond Lee Prim (December 30, 1906 – April 29, 1995), nicknamed "Pop", was an American pitcher who played Major League Baseball during the 1930s and 1940s.

He played for the Washington Senators, for the Philadelphia Phillies, and for the Chicago Cubs while at the Major League level.

As result, though naturally right-handed, he threw with his left-hand, though he batted from the right side of the home plate.

In 1931 Prim played with the Greensboro Patriots and the Durham Bulls of the C-Class Piedmont League.

Kenesaw Mountain Landis, the Commissioner of Baseball, ruled that Albany had the right to sell them to the franchise of their choice.

Prim faced Mickey Cochrane and Jimmie Foxx to start his major league career.

Prim helped the Cubs to make the 1945 World Series with a 13–8 record, an ERA of 2.40 and two shutouts.

Because of his outstanding performance while with the Angels, Prim joined the Pacific Coast League Hall of Fame in 2005.

Prim died on April 29, 1995, in Monte Rio, California, and was buried at the Calvary Cemetery in Los Angeles.
