Ira Felix Thomas (January 22, 1881 – October 11, 1958) was an American professional baseball player. He played all or part of ten seasons of Major League Baseball, all in the American League, with the New York Highlanders (1906–07), Detroit Tigers (1908), and Philadelphia Athletics (1909–15), primarily as a catcher. In 1918, while the great Influenza hammered Philadelphia, Ira volunteered at great personal risk to drive the sick to hospital for treatment.
