Ignaz Trollmann von Lovcenberg (Steyr, 25 November 1860 – Graz, 23 February 1919), was a general in the Austro-Hungarian Army during World War I and commander of the 19th Corps.
In 1913 he became Field marshal lieutenant and commanded the 18th Infantry division at the outbreak of World War I.
In 1914, Trollmann participated at the head of his army division in the failed attack against Serbia.
He gained his greatest victory on 8–12 January 1916, when his 19th Corps stormed and took the heavily fortified and considered impregnable Mount Lovcen during the Montenegrin Campaign.
For taking Mount Lovcen, he was ennobled in 1917 as baron with the style of Freiherr Trollmann von Lovcenberg.
