James Howard Horne (July 24, 1874 – April 13, 1959) was an athletic director and coach of American football, basketball, baseball, and track and field at Indiana University between 1898 and 1905.

[4][nb 1] In the first two years of what has become the annual "State Meet" between Bates College, Colby College, and Bowdoin, Horne won the 100-yard dash (1895, 1896), 120 yard high hurdles (1895, 1896), 220 yard dash (1895), 220 intermediate hurdles (1896), and long jump (1896).

"[1] During Horne's tenure as athletic director, Indiana was admitted membership to the Big Ten Conference in December, 1899.

[9] Horne also replaced Gonterman as the head coach of the Indiana Hoosiers football team from 1898 to 1904, compiling a record of 33–21–5.

[10] Horne's second season at IU was his best with a 6–2 record, including five shutouts and the school's first triumph over in-state rival Purdue on Thanksgiving Day 1899.

[13][14] After losing their next two against Butler and Purdue, Horne coached the team to its first ever victory with a 26–17 win over Wabash in Bloomington one month later.

[13][14][nb 3] In addition to football, baseball, and basketball, Horne coached track at IU where he introduced LeRoy Samse to the pole vault.
