James Edward Beauchamp (/ˈbiː-tʃʌm/ (BE-chum), August 21, 1939 – December 25, 2007) was an American Major League Baseball first baseman and outfielder who played from 1963 to 1973 for the St. Louis Cardinals, Houston Colt .45s/Astros, Milwaukee/Atlanta Braves, Cincinnati Reds, and New York Mets.

A power hitting minor leaguer, Beauchamp had perhaps the best year of his professional career in 1963 for the Double-A Tulsa Oilers, batting .337 with 31 home runs and 105 RBI.

Beauchamp won the 1963 Texas League MVP Award, and a sign showing him in his batting stance stood outside Tulsa's Oiler Park until the stadium was demolished in 1980.

Beauchamp was traded to the Houston Colt .45s in February 1964 with Chuck Taylor for outfielder Carl Warwick.

Beauchamp again dominated in the minors in 1964, belting 34 home runs and collecting 83 RBI with a .285 batting average.

He started the 1965 season with the Houston Astros, playing in 24 games before being traded to the Milwaukee Braves with Ken Johnson for Lee Maye.

In October 1967, Beauchamp was traded with Mack Jones and Jay Ritchie to the Reds for Deron Johnson.

He was traded with Harry Parker, Chuck Taylor and Chip Coulter from the Cardinals to the Mets for Art Shamsky, Jim Bibby, Rich Folkers, and Charlie Hudson on October 18, 1971.

He played his final regular season game on September 20, 1973, almost exactly 10 years after his big league debut.
