The Anti-Corruption Foundation (ACF; Russian: Фонд борьбы с коррупцией (ФБК), romanizedFond borby s korruptsiyey, FBK; lit.'Foundation for combating corruption') is a non-profit organisation established in 2011 by the Russian opposition figure Alexei Navalny. The FBK published investigations into alleged corruption by high-ranking Russian government officials. The organisation is funded by private donations.

On 9 October 2019, the FBK was declared a "foreign agent" by the Russian Ministry of Justice. On 9 June 2021, the FBK was designated as an "extremist" organisation and liquidated by the Moscow City Court. On 11 July 2022, while imprisoned, Navalny announced the relaunch of the FBK as an international organisation. On 27 November 2025, the Russian Supreme Court designated the FBK as a "terrorist organisation".

The European Court of Human Rights and Amnesty International have condemned the Russian Federation's legal actions against ACF and Alexei Navalny, like the designations as "foreign agent", "extremist" and "terrorist", deeming them as politically motivated trial and political and unlawful persecutions.
