Guy Harris "Doc" White (April 9, 1879 – February 19, 1969) was an American left-handed pitcher in Major League Baseball.

Born in Washington, D.C., White was a graduate of the Georgetown University School of Dentistry, hence his nickname "Doc".

[1] White started his professional baseball career in 1901 with the National League's Philadelphia Phillies.

White gained some recognition as a composer, publishing at least four songs (such as bestseller "Little Puff of Smoke, Good Night" in 1910) with his co-writer Ring Lardner, who was a sportswriter in Chicago during that time.

[1] White died at age 89 in Silver Spring, Maryland, just eight months after witnessing Don Drysdale surpass his record of 45 consecutive scoreless innings on June 4, 1968.
