Julia Kathleen Murney (born January 14, 1969) is an American actress and singer, primarily featured in theatre and television commercial voice-overs. Until 2005, she was commonly known as the Broadway actress who had technically never appeared on Broadway. This was due to the fact that her fame came mostly from her performances on the Broadway charity circuit, and not traditional Broadway productions.

Murney's Off-Broadway theatrical credits include originating the role of 'Queenie' in Andrew Lippa's The Wild Party (2000) at the Manhattan Theatre Club, opposite Brian d'Arcy James, Idina Menzel, and Taye Diggs, for which she was nominated for a Drama Desk Award. She was also seen in The Vagina Monologues, Crimes of the Heart (2001), A Class Act (2000), Time and Again (2001), and First Lady Suite. She appeared in a musical version of the film Saved at the Playwrights Horizons Theatre, which had previews starting from May 9, and an opening on June 3, 2008. In August 2008, Murney portrayed the title role of Andrew Lloyd Webber's Evita at Wells Fargo Pavilion in Sacramento.

Murney made her debut on Broadway in 2005, in the short-lived musical Lennon. She was also seen in the Actors' Fund benefit concerts of Funny Girl, Chess, Hair, and the World AIDS Day Benefit Concert Pippin. She has also been featured on television in Sex and the City, Ed, NYPD Blue, and various episodes of Law & Order.
Murney succeeded Stephanie J. Block as Elphaba in the 1st national touring company of the musical Wicked on March 6, 2006. In that role, she won an Acclaim Award from the Cincinnati Enquirer for leading performer in a musical. She departed the tour after six months and was replaced by Shoshana Bean. She then reprised the role of Elphaba in the Broadway production for a nine month engagement, beginning January 9, 2007 where she replaced Ana Gasteyer. She played her final performance as Elphaba on October 7, 2007 and was replaced by Stephanie J. Block.

Her debut solo album, I'm Not Waiting, was released in May 2006 on the Sh-K-Boom Records label. The album's title song was written especially for her by Andrew Lippa, with whom she has a strong artistic relationship. Murney also sings a jazz acoustic version of the song "I'm Not That Girl" from Wicked. She can also be heard on the original cast albums of The Wild Party and A Class Act, and the Actors' Fund recordings of Hair and Chess.
She played Mrs. Walker in The Who's Tommy in Oklahoma City from February 5 - February 21, 2009.
Daughter of actor Christopher Murney and Anne Murney, Julia was named for the song "Julia" from The Beatles White Album. She has a younger sister, Caitlin (born 1977), who is a film producer and lives in LA and younger brother, Patrick (born 1987), who graduated from Syracuse University with a drama degree in 2009.
