Thomas James Hughes (November 29, 1878 – February 8, 1956) was a right-handed starting pitcher in Major League Baseball.

From 1900 through 1913, Hughes played for the Chicago Orphans (1900–01), Baltimore Orioles (1902), Boston Americans (1902–03), New York Highlanders (1904) and Washington Senators (1904–09, 1911–13).

A native of Chicago, Hughes was nicknamed "Long Tom" for his height, a then-impressive 6 ft 1 in (1.85 m).

On August 3, 1906, Hughes became the first pitcher in the modern era (1901 and later) to pitch a shutout and hit a home run that accounted for the only run in the game,[1] when he hit a solo shot in the 10th inning off St. Louis Browns pitcher Fred Glade, at Sportsman's Park II, to give Washington a 1–0 victory.

In a 13-season career, Hughes posted a 132–174 record with 1368 strikeouts and a 3.09 ERA in 2644 innings, including 25 shutouts and 227 complete games.
