The men's horizontal bar event was part of the gymnastics programme at the 1928 Summer Olympics. It was one of seven gymnastics events for men and it was contested for the fourth time after 1896, 1904, and 1924. Scores from the horizontal bar event were added to the results from other individual apparatus events to give aggregate scores for the individual and team all-around events. There were 86 gymnasts from 11 nations, with each nation having a team of up to 8 gymnasts. The event was won by Georges Miez of Switzerland, the nation's first victory in the men's horizontal bar. The silver medal went to Romeo Neri of Italy (the nation's first medal in the event), with Eugen Mack of Switzerland earning bronze.
