Tatjana Ždanoka[3] (Russian: Татьяна Аркадьевна Жданок, Tatyana Arkadyevna Zhdanok; born 8 May 1950) is a Latvian politician and a former Member of the European Parliament.

[4][5][6][7] From 1988 to 1989 she was one of the leaders of the Interfront, a political front organization opposing Latvia's independence from the Soviet Union and rapid market reforms.

[16] In 2004, she ran successfully for MEP as a candidate of the largest Russian political bloc in Latvia[14] becoming a member of the Greens–European Free Alliance fraction in the European Parliament.

[8] On 11 March 2014, Ždanoka and her party organized a rally at the European Commission Representation in Riga in support of the annexation of Crimea by the Russian Federation, with about 200 participants.

[19] In May, Ždanoka proposed European Council to classify Ukrainian political bloc Right Sector as a terrorist organization.

[23] In 2016, Ždanoka voted against the European Parliament resolution of 23 November that condemned the use of disinformation and propaganda by Russia and Islamist terrorist organisations and called for strengthening EU's "strategic communication" task force, as well as investing more in awareness raising, education, online and local media, investigative journalism and information literacy.

[37] On 15 September 2022, she was one of 16 MEPs who voted against condemning President Daniel Ortega of Nicaragua for human rights violations, in particular the arrest of Bishop Rolando Álvarez.

During perestroika, she advocated for economic reform within the Soviet Union and called the pro-independence Popular Front of Latvia "dangerously nationalistic".

[12] For a long time, she opposed the accession of Latvia to the European Union believing that "complete acceptance of the EU's rules would lead to the destruction of our industry and agriculture" and that Latvia should be a "financial bridge between the East and the West" but gave up her Euroscepticism after attending the 2000 New European Left Forum in Sweden.

[41] On March 5, 2019, State Security Service (SSS) launched a criminal procedure over incitement to ethnic hatred or discord for Ždanoka's remarks at a discussion organized by her at the European Parliament, where she likened the situation of ethnic Russians and Russian speakers in Latvia to Jews prior the World War II.

[46][47] Co-chairwoman of the Greens/European Free Alliance Rebecca Harms called Ždanoka's actions and statements as "totally unacceptable" and "in complete and direct opposition with the very clear position the Greens/EFA group has taken since the outset on this issue", calling the European Free Alliance to expel Ždanoka from its ranks.

[48] In 2024, a report from an investigative journalism website The Insider accused Ždanoka of being a spy for Russia's Federal Security Service (FSB) since at least 2004.
