Compartment No. 6 (Finnish: Hytti nro 6; Russian: Купе номер шесть, romanized: Kupe nomer shest) is a 2021 drama road movie co-written and directed by Juho Kuosmanen, starring Seidi Haarla and Yuri Borisov, based on the 2011 novel of the same name by Rosa Liksom.

The film was selected to compete for the Palme d'Or at the 2021 Cannes Film Festival where it shared the Grand Prix with Asghar Farhadi's A Hero. It was selected as the Finnish submission for the Best International Feature Film at the 94th Academy Awards and was one of the 15 "shortlisted" films in the category but was not nominated for the Oscar.

During the Cannes Film Festival, Sony Pictures Classics bought the distribution rights to the film for North America, Latin America, Southeast Asia, the Middle East and Eastern Europe, excluding co-production country Russia, where the film was distributed by the local branch of the sister company, Sony Pictures Releasing, marking the company's second acquisition of a Finnish film following Aki Kaurismäki's The Man Without a Past in 2002.
