List of Portuguese submissions for the Academy Award for Best International Feature Film

Since 1980, Portugal has submitted films for the Academy Award for Best International Feature Film every year but one (1981). The award is given annually by the United States Academy of Motion Picture Arts and Sciences to a feature-length motion picture produced outside the United States that contains primarily non-English dialogue.

Forty Portuguese films have been submitted to the Academy for consideration for the Academy Award for Best Foreign Language Film. As of the 96th Academy Awards, none has been nominated; Portugal holds the record of the most submissions without a nomination in the category. One fifth of Portugal's submissions (8 out of 40) were directed by the prolific Manoel de Oliveira. The Portuguese animated short film Ice Merchants, by João Gonzalez, was nominated for the Academy Award for Best Animated Short Film at the 95th Academy Awards, becoming the first Portuguese film to receive an Oscar nomination.

Submissions
The Academy of Motion Picture Arts and Sciences has invited the film industries of various countries to submit a film for consideration for the Academy Award for Best Foreign Language Film (now Best International Feature Film) since 1956 (before this, it was given as an honorary award from 1947 to 1955). The Foreign Language Film Award Committee oversees the process and reviews all the submitted films, releasing a shortlist of 10 films in mid-December. Following this, they vote via secret ballot to determine the five nominees for the award.

The Portuguese nominee is selected by a jury selected by the Instituto do Cinema e do Audiovisual (in English, the Cinema and Audiovisual Institute). but 2012 was the first year the choice was made by the newly Portuguese Academy of Cinema. All films are in Portuguese except for 2007's French language Belle Toujours. In 2003 Portugal submitted A Talking Picture, which featured a combination of English, French, Greek, Italian and Portuguese. 2013's submission Lines of Wellington was a combination of Portuguese, English and French.
