Malcolm Wayne (Mal) Eason (March 13, 1879 – April 16, 1970) was an American starting pitcher in Major League Baseball who played for the Chicago Orphans (1900–1902), Boston Beaneaters (1902), Detroit Tigers (1903) and Brooklyn Superbas (1905–1906).

His most productive season came in 1906, when he posted a 10–17 mark with a 3.25 ERA. It was Eason's last season as an active player. That July 20, Eason no-hit the St. Louis Cardinals 2–0. Earlier in the season, he had been the losing pitcher in the previous no-hitter to this one, by the Philadelphia Phillies' Johnny Lush on May 1.
