Freiherr Joseph Alvinczi von Borberek a.k.a. Baron József Alvinczi de Borberek (German: Joseph Alvinczy, Freiherr von Berberek; 1 February 1735 – 25 September 1810) was a soldier in the Habsburg Army and a Field Marshal of the Austrian Empire.
An ethnic Magyar, he was born in Transylvania in a place called Alvinc (German: Alwintz), and spent his boyhood in the household of Graf Franz Gyulai before joining his regiment as a Fähnrich aged 14. By 1753 he had risen to Hauptmann.
During the Seven Years' War, Alvinczy distinguished himself leading a Grenadier company in the battles of Torgau and Teplitz, where his courageous leadership won him a promotion to second Major. At the end of the war he worked extensively on the implementation of Franz Moritz von Lacy's new regulations throughout the army.
Promoted to Oberst commanding the 19th Infantry Regiment 19 in 1774, he led his men during the War of the Bavarian Succession, where he took the Böhmertor, city of Habelschwerdt and captured the Prussian Commander Prince Hessen-Philippstal, a feat which won Alvinczy promotion to Major General and award of the Militär-Maria Theresien-Orden (MTO).
