Boris Malagurski (Serbian Cyrillic: Борис Малагурски; born 11 August 1988) is a Serbian-Canadian film director, producer, writer, political commentator, television host, and activist. His films include the documentary series The Weight of Chains.

Born to Branislav Malagurski and Slavica Malagurski, Boris grew up in the northern Serbian town of Subotica. In an interview for Literární noviny, Prague's cultural and political journal, Malagurski said that his last name originates from the Polish town of Mała Góra.

Malagurski emigrated to Canada in 2005 and made a documentary film about his move from Serbia called The Canada Project. Excerpts from the film were shown on Serbian National Television, as a part of Mira Adanja-Polak's TV show. Since then, Malagurski identifies himself as Serbian-Canadian. While studying Film Production at the University of British Columbia, Malagurski organized protests in Vancouver against Kosovo's declaration of independence and received help from Canadian journalist Scott Taylor and Irish diplomat Mary Walsh in making his film about Kosovo. Malagurski became a Canadian citizen and remained in Canada until 2011, when he returned to work in Serbia.

Malagurski attended Kitsilano Secondary School in Kitsilano neighbourhood of Vancouver, British Columbia. Malagurski earned his bachelor's degree in film production from the University of British Columbia. In July 2019, he earned his master's degree in film from the University of Staffordshire.

In 2010, the newspaper Politika described Malagurski as the "Serbian Michael Moore", though Malagurski himself had spoken of his use of "Michael Moore post-production techniques", earlier in the same year.

In 2009, Malagurski released Kosovo: Can You Imagine?, a documentary film about the plight of Serb communities living in Kosovo at that time. Former Canadian general Lewis MacKenzie, Canadian former diplomat James Byron Bissett, former UNMIK officer John Hawthorne and economist Michel Chossudovsky are interviewed in the film.

In 2010, Malagurski released The Weight of Chains, his documentary film analyzing the role that the United States, the European Union, and the NATO alliance as a whole allegedly played in the breakup of Yugoslavia. The film features interviews with James Byron Bissett, John Bosnitch, Michel Chossudovsky, Vlade Divac, Branislav Lečić, Veran Matić, John Perkins, general Lewis MacKenzie and others. The film was shown in cinemas in Australia, Canada, the United States and Serbia, also at the festivals listed below, and on Eurochannel TV networks. In December 2018, the film was added to the film and video catalog of the Library of United States Congress.

Malagurski co-directed (with Ivana Rajović), The Presumption of Justice in 2012, a documentary dealing with the September 2009 death of Brice Taton, a fan of Toulouse FC, and alleged inconsistencies in the subsequent court case in Serbia. The film had its broadcasting premiere in April 2013 as a part of Malagurski's TV show on Happy TV which also featured an interview with a man who claimed to have witnessed the event, but who had not been called to testify.
