George Walter Ball (September 12, 1878 – December 15, 1946) was an American baseball pitcher in the Negro leagues.

Born in Detroit, Michigan, from 1893 he played ten years as the only black player on minor white teams in Minnesota and North Dakota.

In the first season, Ball won 25 out of 28 games, and helped the team win the state baseball championship of North Dakota.

He wintered in Grand Forks, North Dakota and was signed by Frank Leland to play for his Chicago Union Giants in 1903.

During the last half of the season, he was back playing for the Chicago Union Giants, reportedly winning 48 straight games.

Six years after his death, Ball received votes listing him on the 1952 Pittsburgh Courier player-voted poll of the Negro leagues' best players ever.
