Paul Frederick Schreiber (October 8, 1902 in Jacksonville, Florida – January 28, 1982 in Sarasota, Florida) was a pitcher in Major League Baseball. He pitched in ten games for the Brooklyn Robins during the 1922 and 1923 baseball season. He returned to the major leagues as a batting practice pitcher and coach for the New York Yankees. In 1945, while he was coaching for the Yanks, he briefly came out of retirement to pitch in two more games when the staff was depleted due to World War II. He then was a coach for the Boston Red Sox for 13 seasons, from 1946 to 1958, and scouted for them during the 1960s.
