The 2006 protests in Hungary were a series of anti-government protests triggered by the release of Hungarian Prime Minister Ferenc Gyurcsny's private speech in which he confessed that his Hungarian Socialist Party had lied to win the 2006 election, and had done nothing worth mentioning in the previous four years of governing. Most of the events took place in Budapest and other major cities between 17 September and 23 October. It was the first sustained protest in Hungary since 1989.

The Őszöd speech (Hungarian: Őszödi beszéd) was a speech Hungarian Prime Minister Ferenc Gyurcsány delivered to the 2006 Hungarian Socialist Party (MSZP) congress in Balatonőszöd. Though the May congress was confidential, Gyurcsány's address was leaked and broadcast by Magyar Rádió on Sunday, 17 September 2006, igniting a nationwide political crisis.

Liberally using vulgar language, Gyurcsány criticized the MSZP for misleading the electorate and said that its coalition government had enacted no significant measures over its tenure. The mass protests the speech's release precipitated are considered a major turning point in Hungary's post-communist political history. MSZP's inability to contain the speech's political fallout led to the popular collapse of MSZP and, more broadly considered, of the Hungarian political left, paving the way for Fidesz's supermajority victory in the 2010 Hungarian parliamentary elections.
