James Webster Wilhelm (born September 20, 1952) is an American former outfielder in Major League Baseball from 1978 to 1979 for the San Diego Padres. A graduate of Santa Clara University, Wilhelm threw and batted right-handed, stood 6 feet 3 inches (1.91 m) tall and weighed 190 pounds (86 kg).

Chosen in the seventh round of the 1974 Major League Baseball Draft, Wilhelm spent five seasons in the Padres' farm system before his recall in September 1978. In his first game on September 4, Wilhelm doubled off the Atlanta Braves' Larry McWilliams, driving in two baserunners and putting the Padres ahead to stay in a game they would eventually win 8–4.^[1] Although he started the 1979 season in Triple-A, Wilhelm was recalled to San Diego in July and appeared in 39 games over the remainder of the season, batting .243 with 25 hits.

However, just prior to spring training in 1980, on February 15, Wilhelm was traded to the Cleveland Indians with pitcher Bob Owchinko for outfielder Jerry Mumphrey. Rather than report to the Indians, Wilhelm, 27, retired from the game.

His final MLB totals included 49 games played, all with the Padres, with six doubles and three triples among his 32 MLB hits.
