Victoria Pedretti (born March 23, 1995) is an American actress. She gained wide recognition for starring in the Netflix horror series The Haunting of Hill House (2018) and The Haunting of Bly Manor (2020), and in the Netflix thriller series You (2019–2021), emerging as a scream queen. For these roles, she received a MTV Award and nominations at the Critics' Choice and Saturn Awards.

Pedretti's films include the comedy drama Once Upon a Time in Hollywood (2019) as Leslie Van Houten, the biographical drama Origin (2023), the thriller Ponyboi (2024), and the comedy horror Forbidden Fruits (2026). On stage, she has appeared in a Broadway revival of An Enemy of the People (2024) and the play Tender Napalm (2024).

Victoria Pedretti was born on March 23, 1995, in Philadelphia, Pennsylvania. She is of part Italian ancestry. She was raised Jewish, and had a bat mitzvah. She was diagnosed with ADHD when she was seven years old. She first expressed an interest in musical theatre while attending Pennsbury High School in Fairless Hills. She received her Bachelor of Fine Arts at the Carnegie Mellon School of Drama in Pittsburgh, where she said her professors advised her not to pursue acting.

Pedretti began acting in 2014, appearing in the short films Sole as the female protagonist and Uncovering Eden as Edie. Her breakthrough came with playing Eleanor "Nell" Crain in Mike Flanagan's Netflix supernatural horror series The Haunting of Hill House, released in 2018 to critical acclaim. Reviewers at Dread Central and The Guardian called Pedretti's performance "scene-stealing" and the "soul" of the show, and MovieWeb said it added "a horrifying realism to the character, and viewers can feel all of Nell's pain and anguish to the very end. This is one of the defining roles for Victoria Pedretti, and she's only getting started." She received nominations for the Saturn Award for Best Supporting Actress on Television and the MTV Movie Award for Most Frightened Performance.

Pedretti was next cast as Love Quinn in the Netflix thriller series You, having previously auditioned for the role of Guinevere Beck. She stars in season two and three, which were released in 2019 and 2021, respectively, to critical acclaim. While filming during the COVID-19 pandemic, the intimate scenes posed a challenge for Pedretti to film as "it took months to figure out how to do it safely. [...] We played a couple before, but it didn't just immediately come back after being in a global pandemic." For season two, writers at Elle said Pedretti "delivered the perfect amount of spook and smolder to keep us on the edge of our seats for all ten episodes." She was nominated for the MTV Movie Award for Best Villain. Also in 2019, she played Leslie Van Houten in Quentin Tarantino's comedy-drama film Once Upon a Time in Hollywood, her first role in both a feature film and a blockbuster film.

Pedretti next played Evelyn Porter in the 2020 pilot episode of the anthology series Amazing Stories. She also appeared in the short film This is Not a Love Letter and played Katherine in the biographical-drama film Shirley. A follow up series to The Haunting of Hill House, The Haunting of Bly Manor, was released in 2020 and saw Pedretti leading the show as Danielle "Dani" Clayton. Journalists at The Hollywood Reporter and Screen Rant greatly praised her acting, deeming it "star-making", "appealing" and "heavy lifting". Angelica Jade Bastién of Vulture even called Pedretti "one of the most exciting young actors to watch". She won the MTV Movie Award for Most Frightened Performance and was nominated for the Critics' Choice Super Award for Best Actress in a Horror Series.

In 2021, Pedretti appeared in singer-songwriter Kacey Musgraves' Star-Crossed: The Film, a companion feature to Musgraves' album of the same name, in a cameo role as a woman participating in a heist. A clip from the film featuring Pedretti later served as the music video for Musgraves' song "Simple Times". Also in 2021, she was announced to star in the film Lucky, based on the memoir of the same name, in which she would be portraying writer Alice Sebold during her freshman year at Syracuse University. However, the film was cancelled after losing its financing.

Pedretti was announced in 2022 to be headlining the Hulu original series Saint X, but she reportedly left the series due to creative differences, with Alycia Debnam-Carey replacing her in the lead role. The following year, she played Irma Eckler in Ava DuVernay's acclaimed biographical drama film Origin. She also reprised the role of Love Quinn in the fourth season of You as a cameo appearance in 2023.
