荷兰省督（荷兰语：stadhouder 荷兰语读音：[ˈstɑtˌɦʌudər]），又称为「执政」、“事务长”或“代理官”，直译为“持地者”，“持有某人之地”，也许转借自德语“Statthalter”，法语“lieutenant”，或中古拉丁语“locum tenens”。在低地国家，「执政」（荷兰省督）本是一个中世纪的职务，而在18世纪期间，则发展为了如此的一个“有王冠的”荷兰共和国的一个种类罕见的、事实上世袭的国家元首。它可以与法国头衔“Lieutenant（‘持地者’，‘有一定地位的人’，‘在其上级不在场时，拥有一定职务的人’）”以及英格兰的十六世纪的“Lord Lieutenant（‘皇家代理官大人’）”相比较。此外，这个职位在早期的荷兰共和国被分派来维持和平与省份的治安。

In the Low Countries, a stadtholder (Dutch:stadhouder, Dutch pronunciation:[ˈstɑtˌɦʌudər]) was a medieval function, which during the 16th, 17th and 18th centuries developed into a rare type of de facto hereditary head of state of the thus crowned republic of the Netherlands. It is comparable with the French title Lieutenant and England's 16th century Lord Lieutenant. Additionally, this position was tasked with maintaining peace and provincial order in the early Dutch Republic. The Dutch Monarchy is a cognatic descendant of the first Stadtholder of the young Republic, William of Orange. He was the leader of the successful Dutch Revolt against the Spanish Empire.
