Béla Linder (Majs, 10 February 1876 – Belgrade, 15 April 1962), Hungarian colonel of artillery, Secretary of War of Mihály Károlyi government, minister without portfolio of Dénes Berinkey government, military attaché of Hungarian Soviet Republic based in Vienna, finally the mayor of Pécs during the period of Serb occupation.

In 1918, during the so-called "Aster Revolution" his career suddenly rocketed from colonel status to Secretary of War on 31 October 1918.

"[3] The Hungarian Royal Honvéd army still had more than 1.400.000 soldiers[4][5] when Mihály Károlyi was announced as prime minister of Hungary.

Károlyi yielded to U.S. President Woodrow Wilson's demand for pacifism by ordering the unilateral self-disarmament of the Hungarian army.

Under the terms of the armistice, Serbian and French troops advanced from the south, taking control of the Banat and Croatia.

[9][10] Referring to the negotiations with the Entente Cordiale, the Ministry of Military led by Linder sent a telegraph to the Foreign Office on 6 November 1918 to order the German troops onto the banks of Danube and Sava, which they refused.

On 7 November there were already negotiations in Belgrade between the delegation led by Mihály Károlyi and the commander of eastern Entente troops, general Franchet d'Esperey.

The Kingdom of Serbs, Croats and Slovenes and Josip Broz Tito's Yugoslavia honoured him for his activities in the unilateral self-disarmament of the Hungarian WW1 Honvéd army and for his role in the foundation of the Baranya–Baja Serbian–Hungarian Republic between 1918 and 1919, and he received state funeral and an honorary tomb in Belgrade.
