Mark Tkaciuk (; born 26 September 1966) is a Moldovan politician, historian, archaeologist, and anthropologist. He is a former member of the Parliament of the Republic of Moldova and has been active in Moldova's political and academic life.[1]
Tkaciuk was born in 1966 in Soroca, Moldavian SSR. His father, Yevgeny, is of Ukrainian descent, and his mother, Azniv, is of Armenian-Hemshin origin. He graduated from the History Faculty at the State University of Moldova and later pursued further studies at the Russian Academy of Sciences (1992–1994). During this period, he was affiliated with the far-left Confederation of Anarcho-Syndicalists.[2]
Tkachuk joined the Party of Communists of the Republic of Moldova (PCRM) in the early 2000s and became Domestic Policy Advisor to President Vladimir Voronin from 2001 to 2008. He played a central role in modernizing the PCRM and negotiating the party's accession to the Party of the European Left. Tkachuk is known for his support for Moldova's integration into the Eurasian Union and fostering strong ties with Russia, positions that have drawn both support and criticism.[3]
In 2005 and 2006, VIP Magazine included Tkachuk in the list of "most influential Moldovans," ranking 11th and 6th, respectively.[4] [5]
After 2009, as the PCRM entered the opposition, Tkachuk began advocating for reforms within the party, focusing on turning it into a more modern, European-left party.[6] He became known as the "grey eminence" of the party due to his influential role, until his departure in 2014.[7] Tkachuk announced his withdrawal from politics in the same year.[8]
Tkachuk returned to politics in 2019, co-founding the Collective Action Party – Civic Congress alongside Iurie Muntean. The party promotes left-wing, civil-labour oriented policies and has been moderate critical of both the pro-European and pro-Russian political agendas, focusing on issues such as social justice and workers' rights.He supported Alexander Stoianoglo in the presidential election in 2024.

Tkachuk is the chief editor and founder of Stratum Plus, a Q1-rated academic journal specializing in history and archaeology.[14] His academic work extends to archaeological works in Moldova and Bulgaria, and founding the Higher Anthropological School and the Library of Civilizations named after Marc Bloch in Chișinău.
