James Alvin "Jim" Palmer (born October 15, 1945), nicknamed "Cakes," is a former Major League Baseball right-handed starting pitcher who played his entire career for the Baltimore Orioles (1965–1984). He was elected to the Baseball Hall of Fame in 1990.

As of 2008, Palmer and his wife Susan have homes in Palm Beach, Florida, and in California. In 2006, Palmer also acquired a penthouse condominium in Little Italy, Baltimore, which he uses while in Baltimore for Orioles' broadcasts.

Palmer was born in New York, New York; shortly after his birth, Palmer was adopted by Moe Wiesen, a garment industry executive, and his wife Polly from Harrison, N.Y. After his adoptive father died in 1955, the 9-year-old Jim, his mother and his sister moved to California, where he began playing in youth-league baseball. In 1956, his mother married actor Max Palmer, from whom Palmer took his last name. Showing talent at the amateur level, upon graduating from Scottsdale High School, (Scottsdale, AZ) in 1963, Palmer signed a minor-league contract at the age of 18. Before heading to the minor leagues, Palmer was initiated into Sigma Chi at Arizona State University, although he never attended ASU.
