Ekaterina Yuryevna Gubareva[a] (Russian: Екатерина Юрьевна Губарева; born 5 July 1983) is a pro-Russian activist and former public figure.

[1] Gubareva held senior positions in pro-Russian separatist-held territory during the war in Donbas, briefly as the "Minister of Foreign Affairs" in Russian-occupied Donetsk for the Donetsk People's Republic in 2014, and then following the 2022 Russian invasion of Ukraine deputy head of the collaborationist Kherson Military-Civilian Administration in Russian-occupied Ukraine.

"[12][13] On 16 August 2014, Gubareva was demoted, with the former vice president of Transnistria, Alexander Karaman, replacing her in the post of foreign minister of the DPR, for unspecified reasons.

[19] On 16 June 2022, during the Russian invasion of Ukraine, Gubareva took office as Chief of Staff and Deputy Head of the Russian-occupation government called "Kherson Military-Civilian Administration" for Digitalization, Communications, Legal Regulation, and Domestic and Foreign Policy.

[20] In statements made of a planned referendum to join Russia, she claimed that the Russian Federation was repeating the history of Empress Catherine who developed the "wild fields" following the Russo-Turkish War of 1768–1774.

[24] During her public life, due to being a young, blonde, attractive female, on the Russian side, Gubareva was often been compared to former Crimean prosecutor Natalya Poklonskaya.
