Louis Raphael "Bull" Durham (born Louis Raphael Staub; June 27, 1877 – June 28, 1960) was an American pitcher in Major League Baseball.

After he began playing minor league baseball he got into trouble with the league due to a fight in a bar.

He was banned, but found a loophole by changing his name to "Bull Durham", after the Bull Durham Smoking Tobacco brand.

Once he finished his baseball career in 1909, he began acting and had roles in several silent films.

He died in Bentley, Kansas.
