Robert Cleveland Muncrief (January 28, 1916 – February 6, 1996) was an American professional baseball pitcher who appeared in 288 games in Major League Baseball over 12 seasons between 1937 and 1951 with the St. Louis Browns, Cleveland Indians, Pittsburgh Pirates, Chicago Cubs and New York Yankees. Born in Madill, Oklahoma, he batted and threw right-handed and was listed as 6 feet 2 inches (1.88 m) tall and 190 pounds (86 kg). He is perhaps best known as a key starting pitcher for the 1944 Browns, the only American League team from St. Louis to win a pennant. The following season, in 1945, Muncrief led all Junior Circuit hurlers in winning percentage, posting a .765 mark based on his 13–4 record.
