Lajos Aulich (1793, Pozsony (now Bratislava, Slovakia) – 6 October 1849, Arad (now in Romania)) was the third Minister of War of Hungary.
A professional soldier and lieutenant colonel in the Austrian army, he fought against Habsburg oppression.
At them time of the War of Hungarian Independence (1848–1849) during the Spring Campaign, Aulich commanded an army, who gathered, and prepared for the great Battle of Isaszeg.
He was a stickler for the rules: when Lajos Kossuth sent him requests, he answered: "please work through Görgey." Due to his gout, he was relieved of field duty and appointed Minister of War on 14 July 1849.
He was executed less than three months later as one of the 13 Martyrs of Arad.
