Henry Hack Eibel (December 6, 1893 – October 16, 1945) was a utility player in Major League Baseball who played for the Cleveland Naps (1912) and Boston Red Sox (1920). Listed at 5 ft 11 in (1.80 m) and 220 lb., Eibel batted and threw left-handed. He was born in Brooklyn, New York to emigrant parents of German extraction.^[1] Eibel first played in the majors at the age of 18.

During his brief major league career, Eibel did almost everything a player was asked to do, appearing in 30 games, as a relief pitcher (3 games), left fielder (3), right fielder (3), first baseman (1), and pinch-hitter or pinch-runner (20).

In a two-season career, Eibel was a .174 hitter (8-for-43) with four runs and six RBI, including two doubles and one stolen base. He did not hit a home run. In three relief appearances, he posted a 3.48 ERA with five strikeouts and three walks in 10⅓ innings and did not have a decision.

Eibel shot himself to death in Macon, Georgia at age 51.^[2] Macon was also the town of Eibel's final professional ball club team. Eibel retired from baseball in 1924.
