Ewell Albert "Reb" Russell (March 12, 1889 – September 30, 1973) was an American Major League Baseball player for the Chicago White Sox and the Pittsburgh Pirates.

Only Washington's ace Walter Johnson topped Reb's eight shutouts, and Russell tied a record that still stands with five 1–0 victories in a season.

Russell helped the White Sox win the 1917 American League pennant, with a won-loss record of 15–5 and an ERA of 1.95.

He was the starting pitcher of Game 5 of the 1917 World Series, but was unable to retire a batter and was replaced in the first inning by Eddie Cicotte.

Russell remained a highly paid star in the AA through age 40, and won the league batting title (.385) when he was 38 years old.
