Norm Siebern, American baseball player and scout (b. 1933)
Norman Leroy Siebern (July 26, 1933 – October 30, 2015) was an American professional baseball player and scout. He appeared in 1,406 games over a 12-year career in Major League Baseball as a first baseman and left fielder for the New York Yankees, Kansas City Athletics, Baltimore Orioles, California Angels, San Francisco Giants and Boston Red Sox between 1956 and 1968. A two-time World Series champion and four-time American League All-Star, his best season came in 1962 with the Athletics, when he hit 25 home runs, had 117 runs batted in and a .308 batting average. He might be most remembered, however, as being one of the players the Yankees traded for Roger Maris on December 11, 1959.

Siebern was born in St. Louis, where he graduated from Wellston High School. He attended Missouri State University (then known as Southwest Missouri State) and Washington University in St. Louis, and was signed by Yankees scout Lou Maguolo in 1951. Siebern batted left-handed, threw right-handed, and was listed as 6 feet 2 inches (1.88 m) tall and 200 pounds (91 kg).
