Derussification in Ukraine is a process of removing Russian influence from Ukraine. This derussification started after the fall of the Soviet Union in 1991. The speed of derussification increased with the demolition of monuments and statues of Lenin during the Euromaidan protests in 2014. The Russo-Ukrainian War increased the speed of derussification in Ukraine.
The process is done by renaming everything named after Russian statesmen, cultural figures, and of everything that were believed to reflect the Russian worldview, or anything related with Russia. As of 8 April 2022, according to a poll by the group Rating, 76% of Ukrainians support the renaming of streets and other objects whose names are associated with Russia.
In March 2023, the Ukrainian parliament passed the Law of Ukraine "On the Condemnation and Prohibition of Propaganda of Russian Imperial Policy in Ukraine and the Decolonization of Toponymy", which forbade the study of place names associated with Russia.
On 21 April 2023, President Volodymyr Zelenskyy signed the law. This law prohibits studying of name of places that praises or glorifies Russia, people who did on war against Ukraine or any other country. A series of places have already been renamed based on this law.
The process of derussification started with the fall of the Soviet Union, but since the issue of decommunization was a huge problem, derussification only received little attention. After the 2014 Crimean War, derussification started to grow. The decommunization process in Ukraine was almost been completed by 2022, the derussification process became faster after the Russian war of Ukraine.
On 28 February 2018, the Constitutional Court of Ukraine issued a decision and cancelled the Kolesnichenko-Kivalov Law. The law had earlier accepted Russian and other minority languages as regional languages of Ukraine. Due to this rule, minority languages like Russian was allowed to be used in courts, schools and other government institutions in Ukraine where the minorities had their population more than 10%.
On 23 October 2020, the Zaporizhzhia District Administrative Court refused to grant the Russian language the status of regional language in the city of Zaporizhzhia.

On 25 October 2016, the Lviv Oblast Council evicted the Russian Cultural Center and rent the premises to groups that are involved in the Ukrainian army's operations in eastern Ukraine against pro-Russian separatists, such as in Donetsk and Luhansk.
