Harvey Max "Hob" Hiller (May 12, 1893 – December 27, 1956) was an American Major League Baseball utility player for the Boston Red Sox in 1920 and 1921.

[3] Hiller first played professional baseball in the North Carolina State League with the 1915 Durham Bulls as a third baseman.

[5] In a June 1st game against the Jacksonville Roses, Hiller was struck in the head by a pitch, which put him into a semiconscious state but did not fracture his skull.

[2][3] Hiller signed a contract with the Red Sox on January 4, 1920, and joined the team for spring training.

[3] He made his major league debut on April 22, 1920,[1][6] in a game against the Washington Senators as a midgame substitution.

[6] On July 15, 1920, the Red Sox traded Hiller and catcher Paddy Smith to the Pittsfield Hillies of the Eastern League for Cliff Brady.

[3] Whereas in the spring Hiller had primarily been used as a substitute shortstop, second baseman, and pinch runner, in September he started several games at third base.

[6] During the month of September, Hiller recorded four hits, including a double and a triple, but was also caught stealing three times.

[3] As their third baseman, Hiller played in 122 games and got 104 hits, including 18 doubles, three triples, and two home runs, for a batting average of .259 and a slugging percentage of .336.
