Dermot Mulroney was born in Alexandria, Virginia. His mother, Ellen B. (née Goen), was a housewife and amateur actress originally from Manchester, Iowa, and his father, Michael Mulroney, was a law professor (and amateur racecar driver) at Villanova University School of Law, originally from Elkader, Iowa. He has a sister, Moira, and three brothers, Conor, Kieran (who is also an actor), and Sean. Moira formerly worked in the Philadelphia DA's office as an assistant district attorney and later at WXPN, an FM radio station in Philadelphia, but now works elsewhere in the non-profit industry.
Some of Mulroney's ancestors immigrated from County Donegal and County Mayo in Ireland during the Irish Potato Famine; he is of mostly Irish descent, with more distant German ancestry. Mulroney attended Maury Elementary School and played cello in school and city youth orchestras, as well as acting in children's community theater. Mulroney attended the Interlochen Arts Camp as a cellist. He later attended T. C. Williams High School (grad. 1981) as well as Northwestern University (grad. 1985) in Evanston, Illinois, where he was a member of the fraternity of Phi Gamma Delta.
