Joshua Daniel Hartnett (born July 21, 1978) is an American actor.

Hartnett continued to work steadily throughout the 2000s, with a mix of leading and supporting roles in Hollywood Homicide (2003), Wicker Park (2004), Sin City (2005), The Black Dahlia, Lucky Number Slevin (both 2006), 30 Days of Night (2007), August (2008), and I Come with the Rain (2009). He experienced a career resurgence with his roles as Ernest Lawrence in Oppenheimer (2023) and a serial killer in Trap (2024).
On television, Hartnett portrayed Ethan Chandler on the Showtime fantasy series Penny Dreadful (2014–2016). He also appeared in an episode of Black Mirror in 2023 and guest-starred on The Bear from 2024 to 2025.
After Hartnett graduated from high school in 1996, he moved to Purchase, New York, to attend the Conservatory of Theatre Arts & Film at the State University of New York at Purchase. He was expelled after writing a letter to the dean contending that the college's evaluation system stifled students' creativity. At the age of 19, Hartnett moved to Los Angeles at the recommendation of his manager, Nancy Kremer, who had previously helped him book television commercials.
Hartnett then developed a successful film career, appearing in the major films The Faculty (1998), The Virgin Suicides (1999), and Black Hawk Down (2001). In 2001, he starred in the war drama Pearl Harbor. He was originally scheduled to play the role of Tino in Deuces Wild, but dropped out to star in Pearl Harbor. Also in 2001, he starred in O, an adaptation of William Shakespeare's Othello set in an American high school, as Hugo, the film's version of Iago. In 2002, he starred in the romantic comedy 40 Days and 40 Nights.
In the early 2000s, Hartnett was approached several times to play the role of Clark Kent / Superman for a project originally helmed by Brett Ratner but always turned it down, not wanting to commit to a predicted ten-year role. Hartnett said of his decision, "It just wasn't the kind of movie I wanted to do. I turned down other superhero roles as well." He was also considered for, but not offered, the role of Batman in Christopher Nolan's Batman Begins, which ultimately went to Christian Bale .
Hartnett was chosen as one of Teen Peoples "21 Hottest Stars Under 21" in 1999, Teen Peoples "25 Hottest Stars under 25", and one of Peoples "50 Most Beautiful People", both in 2002. He was also voted Bliss magazine's "3rd Sexiest Male". During this period, he was marketed as a teen idol and a potential Megastardom; his unease with this public image eventually led to his disillusionment with pursuing roles in high-profile films.
Hartnett's next films included Hollywood Homicide (2003), Wicker Park (2004), Mozart and the Whale (2005), Sin City (2005), and Lucky Number Slevin (2006). He followed up these roles with the 2006 drama-mystery The Black Dahlia, in which he played a detective investigating the notorious real-life murder of waitress Elizabeth Short. Hartnett had been cast in the role five years before the film was produced, remaining committed to appearing in the movie because he liked the subject matter.
Among his 2007 roles were Resurrecting the Champ and the graphic novel-based 30 Days of Night, in which he played a small-town sheriff. Hartnett described the second film as "supernatural, but kind of a western". He was going to play trumpet player Chet Baker in the film The Prince of Cool but did not agree with the producer's ideas and left the project.
In 2008, Hartnett played Charlie Babbit in the theater adaptation of Barry Morrow's Academy Award-winning Rain Man at the Apollo Theatre in London's West End. He starred in the new campaign of the Emporio Armani fragrance, "Diamonds for Men", being featured in both print and TV ads for the fragrance, thus becoming the first male celebrity to represent Giorgio Armani.

In 2011, Hartnett became one of a handful of celebrities attached to USAID and Ad Council's FWD campaign, an awareness initiative tied to that year's East Africa drought. He joined Uma Thurman, Chanel Iman and Geena Davis in TV and Internet ads to "forward the facts" about the crisis.

He along with Minneapolis Mayor RT Rybak also appeared at the University of Minnesota's McNamara Alumni Center for an Obama Q&A in April.
Regarding fame, Hartnett has said: "I know what it's like to be in that whole world. I was up there for a couple of years, and it was uncomfortable. I think trying to stay at the top is a shortcut to unhappiness." Hartnett took a 15-month break from acting, saying: "I spent a bit of time really thinking about whether this was the right thing for me." "He'll stay out of limelight" . Evening Chronicle. September 10, 2004. Retrieved May 12, 2013.
