Portman portrayed Jacqueline Kennedy in the biopic Jackie (2016), about Kennedy's life immediately after the 1963 assassination of her husband.
She was initially intimidated to take on the part of a well-known public figure, and eventually researched Kennedy extensively by watching videos of her, reading books, and listening to audiotapes of her interviews.
She also trained with a dialect coach to adapt Kennedy's unique speaking style.
David Rooney of The Hollywood Reporter termed it an "incandescent performance" and added that "her Jackie is both inscrutable and naked, broken but unquestionably resilient, a mess and yet fiercely dignified".
She won the Critics' Choice Movie Award for Best Actress and received a nomination for the Academy Award for Best Actress.
She also served as producer for the comedy horror film Pride and Prejudice and Zombies, directed by Burr Steers, and starred in Rebecca Zlotowski's French-Belgian drama Planetarium.
The 2017 experimental romance Song to Song marked Portman's second collaboration with Terrence Malick, which like their previous film polarized critics.

In 2018, Portman starred in the science fiction film Annihilation, based on Jeff VanderMeer's novel.
She played a biologist and former soldier who studies a mysterious quarantined zone of mutating organisms.
She was pleased to headline a rare female-led science fiction film, and she moved her family near Pinewood Studios during filming.
For the action sequences, she underwent movement training with the dancer Bobbi Jene Smith.
Benjamin Lee of The Guardian took note of Portman's "strong, fiercely compelling presence" and commended her for playing the part without unnecessary sentimentality.
It only received a limited theatrical release and was distributed on Netflix internationally.
Her next appearance was in Xavier Dolan's first English-language film, the ensemble drama The Death & Life of John F. Donovan (2018), which was termed a "shocking misfire" by Eric Kohn of IndieWire.
She then starred as a troubled pop singer in Vox Lux, sharing the part with Raffey Cassidy.
She was attracted to the idea of showcasing the negative effects of fame, and in preparation, she watched documentaries on musicians and listened to the music of Sia, who composed her songs in the film.
For the climactic dance routines, she trained with her husband, Benjamin Millepied, who choreographed the sequence.
It received mixed reviews but Portman's performance was picked up for praise.
Comparing it to her portrayals in Black Swan and Jackie, Robbie Collin of The Daily Telegraph wrote that "this role has a similar audacity and extravagance that few actresses would dare attempt, let alone be allowed to get away with".

Unused footage from Thor: The Dark World and a new voice-over was used for Portman's brief appearance in the 2019 superhero film Avengers: Endgame.
She then portrayed a psychologically troubled astronaut (based on Lisa Nowak) in the drama Lucy in the Sky, directed by Noah Hawley.
She replaced the film's producer Reese Witherspoon, who backed out due to a scheduling conflict.
Although Portman's performance was picked up for praise, the film was unfavorably reviewed.
The following year, she narrated the Disney+ nature documentary Dolphin Reef.
Portman will next reprise her role as Jane Foster in Thor: Love and Thunder, which is set to be released in 2021.
