The Marxist Tendency (; MT) was a Trotskyist organization in Russia, created in May 2019 as a result of the merger of the Russian section of the International Marxist Tendency with a faction of the Revolutionary Workers' Party. According to its own statements, the MT is a communist organization that is "working to create national sections of the IMT in the territory of the former USSR."
The movement participated in the 2021 protests and the 2022 anti-war protests, and also condemned the intervention of the CSTO forces in protest-ridden Kazakhstan.
In May 2023, the unification congress of the Marxist Tendency and the communist organisation the New Reds (; NK) was held. The new association was called the Organisaton of Communists Internationalists and became the Russian section of the IMT.
