Charles Thomas Wagner (December 3, 1912 – August 31, 2006) was an American right-handed pitcher in Major League Baseball who played his entire, 100-game career for the Boston Red Sox (1938–42, 1946).

Nicknamed "Broadway," after his playing retirement he went on to a 60-year career as a farm system supervisor, scout, major-league pitching coach and minor-league instructor.

Wagner finished with a 12–8 record and three shutouts, and his 3.07 earned run average was the best on the Boston pitching staff and the third best in the American League, being surpassed only by Thornton Lee (2.37) and Al Benton (2.97), and over Marius Russo (3.09).

Wagner returned to the Red Sox in 1946, along with teammates Ted Williams, Dom DiMaggio, Bobby Doerr, Johnny Pesky, Tex Hughson and Joe Dobson.

He later worked as a special assignment instructor in the Red Sox minor league system, and was still consulted about the organization's prospects into his 90s.
