Winford Ansley Kellum (April 11, 1876 - August 10, 1951) was a starting pitcher in Major League Baseball who played between and for the Boston Americans (1901), Cincinnati Reds (1904) and St. Louis Cardinals (1905). Listed at 5'10", 190 lb., Kellum was a switch-hitter and threw left-handed.

Kellum rebounded in 1902, going 25–10 with the minor league Indianapolis Indians, champions of the newly formed American Association. After the regular season, he pitched with barnstormers largely made up of Cincinnati National League team. After that, he enjoyed his best season in the majors with the 1904 Reds, going 15–10 while recording career-highs in ERA (2.60), complete games (22) and innings (224). He also pitched for the Cardinals in 1905, his last major league season, and went 3–3 with a 2.92 ERA.
In a three-season career, Kellum posted a 20–16 record with a 3.01 ERA in 48 appearances, including 37 starts, 32 complete games, two shutouts, two saves, 97 strikeouts, 63 walks, and of work.
