Robert Garnett "Buddy" Blattner (February 8, 1920 – September 4, 2009) was an American table tennis and professional baseball player.

He played five seasons in Major League Baseball (MLB), primarily for the New York Giants.

Blattner turned to broadcasting after his retirement as a player, teaming with Dizzy Dean on St. Louis Browns radio as well as nationally on the Liberty and Mutual networks, and on the televised baseball Game of the Week on ABC (1953–54) and CBS (1955–59).

Blattner continued to broadcast baseball for the Cardinals (1960–61), Los Angeles/California Angels (1962–68), and Kansas City Royals (1969–75) as well as on NBC's coverage of the 1964 and 1967 All-Star Games.

In 1962, Blattner founded the "Buddy Fund", a charitable organization that supplies athletic equipment to disabled and underprivileged children in the St. Louis area.
