Kenneth Henry Landenberger (July 29, 1928 – July 28, 1960) was an American professional baseball player and manager. Landenbeger played 11 seasons (1948–58) of minor league baseball and managed in the minors for three full seasons and part of a fourth. In his only Major League Baseball service, he appeared in two games as a first baseman and pinch hitter over a nine-day period for the 1952 Chicago White Sox, batted five times, and had one single — off Dick Littlefield of the St. Louis Browns in his final MLB plate appearance.
