James Bentley "Cy" Seymour (December 9, 1872 in Albany, New York – September 20, 1919 in New York, New York) was an American center fielder and pitcher in Major League Baseball. From 1896 through 1913, Seymour played for the New York Giants (1896–1900, 1906–1910), Baltimore Orioles (1901–1902), Cincinnati Reds (1902–1906) and Boston Braves (1913). He batted and threw left-handed.
Seymour enjoyed his best season in 1905, when he led the National League in batting average (.377), hits (219) RBIs (121), doubles (40), triples (21) and slugging percentage (.559). He would have won the Triple Crown but he finished second in home runs with 8, behind Fred Odwell's 9; it was one of Odwell's only two full seasons.
Seymour also set a record which has been tied but never beaten, four sacrifice flies in one game (July 25, 1902).
In a 16-year career, Seymour hit 52 home runs with 799 RBIs and a .303 average (1723 for 5682). He also collected 222 stolen bases.
