指稱哈布斯堡王朝的男性領袖。享有王權的大公之頭銜（德語為「Pfalz-Erzherzog」）首次由奧地利公爵魯道夫四世（Rudolf IV）所使用，目的為使奧地利的公爵得到跟神聖羅馬帝國的選侯相同的地位。該詞彙也使用於指稱西班牙波旁王朝的國王和王后們，即使他們不是出身於哈布斯堡男方直系的繼承者。該詞彙也用於指稱其他歐洲大陸國家的統治者，包含洛林（Lorraine）、布拉班特（Brabant）和奧斯特拉西亞（Austrasia）。大公的妻女則稱為「女大公」。

女大公(奧匈帝國貴族)

英文....	Refers to male heads of the house of Habsburg. The title of archduke Palatine (in German, "Pfalz-Erzherzog") was first assumed by Rudolf IV, Duke of Austria, with the goal of gaining for the dukes of Austria an equal status with the electors of the Holy Roman Empire. The term was also used to refer to the Bourbon kings and queens of Spain, even though they were not descended in the male line from their Habsburg predecessors. The term may also be used to refer to rulers of other Continental European states, including Lorraine, Brabant, and Austrasia. For the wives and daughters of archdukes, use "archduchesses."
荷蘭語....	Te gebruiken voor de zoons en erfgenamen van de voormalige Habsburgse keizers van Oostenrijk en Oostenrijk-Hongarije en tevens voor de voormalige heersers van bepaalde Europese staten, zoals Lorraine, Brabant en Austrazië.
西班牙語....	Usese para los hijos y herederos de los antiguos emperadores Habsburgo de Austria y del Imperio Austro-Húngaro, también para los antiguos regentes de ciertos estados de Europa continental tales como Lorena, Brabante y Austrasia. Para esposas, e hijas de archiduques, use archiduquesa.
