This is a list of submissions to the 91st Academy Awards for the Best Foreign Language Film. The Academy of Motion Picture Arts and Sciences (AMPAS) has invited the film industries of various countries to submit their best film for the Academy Award for Best Foreign Language Film every year since the award was created in 1956. The award is presented annually by the Academy to a feature-length motion picture produced outside the United States that contains primarily non-English dialogue. The Foreign Language Film Award Committee oversees the process and reviews all the submitted films.

For the 91st Academy Awards, the submitted motion pictures must have first been released theatrically in their respective countries between 1 October 2017 and 30 September 2018. The deadline for submissions to the Academy was 1 October 2018. 89 countries submitted films, and 87 were found to be eligible by AMPAS and screened for voters. Malawi and Niger submitted films for the first time, while Belarus made a submission for the first time since 1996. After the 9-film shortlist was announced on 17 December 2018, the five nominees were announced on 22 January 2019.

Mexico won the award for the first time with Roma by Alfonso Cuarón, which also won Best Cinematography and Best Director, and was also nominated for Best Picture, Best Actress (Yalitza Aparicio), Best Supporting Actress (Marina de Tavira), Best Original Screenplay, Best Production Design, Best Sound Editing and Best Sound Mixing.
