Yael Stone is an Australian actress. She has worked extensively in Australian theatre and has won two Sydney Theatre Awards. Outside of Australian theatre, she is perhaps best known for her portrayal of Lorna Muccio née Morello in the Netflix series Orange Is the New Black.
Stone was born and raised in Sydney, Australia, where she attended the Newtown High School of the Performing Arts and the National Institute of Dramatic Art (NIDA).
Stone began acting as a child, with roles in the film Me Myself I and the miniseries The Farm. She worked primarily in theatre; at the 2008 Sydney Theatre Awards, she won the awards for Best Newcomer and Best Supporting Actress for her performance in The Kid. She also worked in television, including supporting roles in All Saints and Spirited. From 2010 to 2011, she appeared in The Diary of a Madman, a role for which she was again nominated for Best Supporting Actress at the Sydney Theatre Awards. In February 2011, she travelled to New York to perform in the Brooklyn Academy of Music's production of The Diary of a Madman, before returning to lead roles in A Golem Story, Summer of the Seventeenth Doll, and As You Like It in Sydney.
Stone moved to New York permanently in December 2011, also co-founding an experimental theatre company. After four months in New York, she was cast in the Netflix series Orange Is the New Black, a show set in a women's prison. Stone plays Lorna Morello, a prisoner from New Jersey; her accent, a mixture of Brooklyn and Boston, was called "the most amazing accent on television" by a journalist for The New Republic, while another reviewer deemed the role to be Stone's "breakout turn". She reprised her role in the show's second season, and was now billed as a series regular.
Stone is Jewish. Her brother, Jake Stone, is the lead singer of the band Bluejuice. Her sister, Elana Stone, is also a musician. In 2012, Stone married Australian actor Dan Spielman, with whom she lives in New York. She divorced a few years later, in 2016. In 2017, it was announced she was expecting her first child with her partner Jack Manning Bancroft. Their daughter Pemau Stone Bancroft was born on May 30, 2018.
