哈布斯堡君主国（德语：Habsburgermonarchie，英语：Habsburg Monarchy），或哈布斯堡帝国（Habsburg Empire），是由历史学家采用的，用来形容一系列曾经由哈布斯堡家族（House of Habsburg）的奥地利系统统治到1780年，而后由继任的家族支系哈布斯堡—洛林家族统治至1918年的国家与省份的非正式名称。这一国家是由神圣罗马帝国体系内外的不同地域组成的，在同一位君主统治下的复合君主国。国家首都除1583年至1611年间位于布拉格外均位于维也纳。从1804年至1867年，哈布斯堡君主国正式统合成奥地利帝国，从1867年至1918年则为奥匈帝国。

The Habsburg Monarchy (German:Habsburgermonarchie) or Empire, occasionally also styled as the Austrian Monarchy (Österreichische Monarchie) and Danubian Monarchy (Donaumonarchie), is an unofficial appellation among historians for the countries and provinces that were ruled by the junior Austrian branch of the House of Habsburg until 1780 and then by the successor branch of Habsburg-Lorraine until 1918. The Monarchy was a composite state composed of territories within and outside the Holy Roman Empire, united only in the person of the monarch. The dynastic capital was Vienna, except from 1583 to 1611, when it was moved to Prague. From 1804 to 1867 the Habsburg Monarchy was formally unified as the Austrian Empire, and from 1867 to 1918 as the Austro-Hungarian Empire.
