George Elvin Walberg (July 27, 1896 – October 27, 1978) was an American professional baseball player.
He played in Major League Baseball as a pitcher, most notably as a member of the Philadelphia Athletics dynasty that won three consecutive American League pennants from 1929 to 1931 and, won the World Series in 1929 and 1930.
He played from 1923 through 1937 for the New York Giants (1923), Philadelphia Athletics (1923–1933) and Boston Red Sox (1934–1937).
