George Frederick "Silent George" Twombly (June 4, 1892 – February 17, 1975) was a Major League Baseball player. He played five seasons with the Cincinnati Reds (1914–1916), Boston Braves (1917), and Washington Senators (1919). He was the older brother of Clarence "Babe" Twombly, who played for the Chicago Cubs in the early 1920s. In 1911, then minor league Baltimore Orioles manager Jack Dunn signed the 18-year-old Twombly out of a Boston high school and sent him to the B-League Scranton Miners.
