Major Grom: Plague Doctor (Russian: Майор Гром: Чумной Доктор, romanized: Mayor Grom: Chumnoy Doktor) is a 2021 Russian action film directed by Oleg Trofim, based on the comic book series of the same name by the Russian publisher Bubble Comics, created by Artyom Gabrelyanov. It is the second film adapted from Bubble Comics, as well as the first feature-length film based on a Russian comic. Prior to that, the studio had released the short film Major Grom. It stars Tikhon Zhiznevsky in the lead role, alongside Lyubov Aksyonova, Aleksei Maklakov, Aleksandr Seteykin, Sergei Goroshko, and Dmitry Chebotaryov. The film is set in Saint Petersburg and tells the story of police major Igor Grom, an honest and skilled cop with unconventional methods, who pursues a vigilante murderer in the mask of a plague doctor.

A teaser for the film was first screened on 30 September 2017 at IgroMir / Comic-Con Russia 2017, after which the project faced difficulties in production for some time, with the team being disbanded and reassembled, and the concept of the film redone from scratch. Three years later, a full trailer was shown at Comic Con Russia 2020, with a tentative release date. Major Grom: Plague Doctor premiered on 25 March 2021 in St. Petersburg. The online premiere took place on 5 May 2021 on KinoPoisk HD and Netflix.

Major Grom: Plague Doctor received a moderately positive reception from critics: the overall quality of the work was noted, but the clichéd and unoriginal plot was also criticised. Some observers have claimed that the film denounces the Russian opposition and praises the police, but not all reviewers agreed with this opinion; the authors themselves have denied these allegations in several interviews. The film failed at the box office, collecting only 328 million rubles in the CIS, with a budget of 640 million rubles, but it proved popular on Netflix and Kinopoisk HD.
