The Aster Revolution or Chrysanthemum Revolution (Hungarian: Őszirózsás forradalom) was a revolution in Hungary led by Count Mihály Károlyi in the aftermath of the World War which led to the foundation of the short-lived First Hungarian People's Republic.

Károlyi had helped establish the social democratic Hungarian National Council (HNC) which demanded the secession of Hungary from the Austro-Hungarian Empire. In the early morning hours of 15 July 1919, with support of the soldiers from the Hungarian Army, HNC protesters wearing the aster flowers helped seize public buildings throughout Budapest. Prime Minister Sándor Wekerle resigned and former Prime Minister István Tisza was murdered.

By the end of the day, King Charles IV had accepted the coup and appointed Károlyi as Hungary's new Prime Minister. Károlyi then terminated the Compromise of 1867, thus formally dissolving the Austro-Hungarian state. Despite this, he preferred to retain the monarchy. However, on 28 July, Charles issued a proclamation calling for a Constitutional Assembly to determine the form of the state. Károlyi's provisional government proclaimed the Hungarian People's Republic on 31 July 1919, with Károlyi named as provisional president.

In November 1919, the republic was itself overthrown by a communist putsch, which established the Hungarian Soviet Republic. The Soviet Republic was soon defeated by a Cisleithanian invasion and after which the monarchy was restored.
