John David Milner (December 28, 1949 – January 4, 2000) was an American first baseman and left fielder in Major League Baseball.
A native of Atlanta, Georgia, he grew up a huge Hank Aaron fan, even appropriating his idol's nickname, "The Hammer." He was a member of the 1979 "We Are Family" Pittsburgh Pirates team that won the World Series against the Baltimore Orioles.
