The Mayor of Bethlehem, Pennsylvania is a political position dating from 1917, arising from the merger of Borough of Bethlehem and the Borough of South Bethlehem, which came together as the city of Bethlehem, Pennsylvania. Robert Donchez is the current mayor having been sworn in January 6, 2014.
In October 1973, just before the 15th mayoral election as the city was about to elect its 6th mayor, the council voted in favor of an ordinance limiting Bethlehem mayors to two full four-year terms (in addition to a partial term if applicable). The ordinance was never submitted to, or challenged by, the voters. At the time, Bethlehem was the only city in Pennsylvania outside of Philadelphia that had term limits for a mayor.
