James Peter Pisoni (August 14, 1929 – February 4, 2007) was (mostly) a backup centerfielder for four teams between 1953 and 1960. Jim was born in St. Louis, Missouri.

Pisoni will forever be known among baseball fans and historians as the last player to debut in a St. Louis Browns uniform. He was signed by the Browns before the 1949 season, but he spent two years in the military during the Korean War before joining St. Louis on September 25, 1953, becoming the last rookie to debut with the Browns before they moved to Baltimore and became the Orioles. He appeared in all three remaining games, including playing in the Browns closer on September 29.

However, Pisoni never played for Baltimore. He went back to the minor leagues and three years later the Orioles traded him to the Kansas City Athletics. He played for them from 1956 to 1957, before joining the Milwaukee Braves (1959) and New York Yankees (1959–60).

Following his baseball retirement, he worked as an electrical contractor.
