Tatyana Doncheva Toteva (Bulgarian: Татяна Дончева Тотева; born 28 January 1960) is a Bulgarian politician from the Movement 21 political party, of which she is the chairperson. She has been a member of four National Assemblies.^[1] - the 38th, 39th, 40th and 45th.

Receiving an education in the field of legal studies (graduating from the juridical faculty of Sofia University), Doncheva has worked as a jurist, lawyer and prosecutor in Sofia. She is also a member of the Arbitration Commission of the Bulgarian Rhythmic Gymnastics Federation.^[2] In 2005, she was a candidate (backed by BSP and a number of other parties) to become mayor of the capital city, losing out to Boyko Borisov in the second decisive electoral round of the municipal elections.^[3] After being unable to stake a strong enough claim for the leadership position of BSP at the party congress in October 2009, Doncheva founded the PP "Movement 21" in April 2010, which does not constitute a political party, but represents the activism of citizens. Tatyana Doncheva ran in the 2016 Bulgarian Presidential Elections.^[4]

She speaks English and Russian in addition to her native Bulgarian.^[5]

Tatyana Doncheva is a vocal opponent against corruption and argues in favor of reforms in Bulgaria's justice system. Recently, she raised concern about the anti-constitutional amendments to Bulgaria's Code of Criminal Procedure which were passed by the Bulgarian Parliament in August 2017.^[6] Doncheva was worried that the new changes create more possibilities for repression: for instance, one of the new provisions permits an investigation to be kept open indefinitely.^[7]

Previously, she had argued that Bulgaria's Prosecution acts like "a shah from the Middle Ages."^[8] She also warned that Bulgaria's Prosecutor General Sotir Tsatsarov abuses his office and attacks businessmen for personal reasons.^[9] In the summer of 2017, Doncheva suspected that Tsatsarov was working towards extending his already excessive powers through negotiations behind the curtain.^[10] Sotir Tsatsarov has recently been nominated for sanctions under the US Magnitsky Act.^[11]
