Robert Arthur Whitcher (April 29, 1917 – May 8, 1997) was an American Major League Baseball pitcher who appeared in nine games for the Boston Braves in 1945.

Whitcher is one of many ballplayers who only appeared in the major leagues during World War II.

He made his major league debut in relief on August 20, 1945 against the St. Louis Cardinals at Braves Field.

He started three games for Boston, and though he pitched effectively overall, the sixth-place Braves lost all three.
