Major Grom (Russian: Майор Гром, romanized: Mayor Grom) is a 2017 Russian short action film directed by Vladimir Besedin, based on the comic character Major Grom.

Plans to make a film were announced at Comic-Con Russia in October 2015, when Bubble Comics announced the creation of its own film division, Bubble Studios. The script was completed on 23 February 2016. The filming process began in mid-August in Saint Petersburg and continued until 28 August 2016.

The short film had its world premiere at the Berlin International Film Festival on 11 February 2017 as test footage for a full-length film production, to be released in 2018. It later became available for general public viewing on 21 February 2017 through Bubble Comics' YouTube channel and on the site Life.ru, the latter gaining more than 1.7 million views on the first day of the film's release there. On 9 March 2017, it was screened on the Russian television station Channel One. On 21 July 2017, the short film was screened during San Diego Comic-Con and included a Q&A session with its creators—Vladimir Besedin, Artyom Gabrelyanov, and Roman Kotkov.

The story is about a major in the MVD of St. Petersburg, Igor Grom, who tries to stop the robbery of a bank, save the hostages, and arrest a gang of three bandits hiding their identity under the masks of characters from the Soviet cartoon Puck! Puck!.
