The 1898 Sewanee Tigers football team represented Sewanee: The University of the South during the 1898 Southern Intercollegiate Athletic Association football season. The team was coached by John Gere Jayne in his second year as head coach, compiling a record of 4–0 (3–0 SIAA) and outscoring opponents 56 to 4 to win the Southern Intercollegiate Athletic Association title. Due to misgivings over Virginia and North Carolina playing ringers, Caspar Whitney declared Sewanee the best team in the South.
