Dianna Elise Agron (; born April 30, 1986) is an American actress, singer and dancer. After primarily dancing and starring in small musical theater productions in her youth, Agron made her screen debut in 2006. From 2006 to 2007 she had recurring roles on Veronica Mars as Jenny Budosh and Heroes as Debbie Marshall, landing her first leading role as Harper on the MTV series It's a Mall World in 2007. Between 2007 and 2009 she had several lead and supporting roles in comedy films; in 2009 she took the notable role of the antagonistic but sympathetic head cheerleader Quinn Fabray on the Fox musical comedy-drama series Glee. For her role in the series she has won a SAG Award and was nominated for three Grammy Awards and one Brit Award, among other accolades. After Glee proved to be a breakthrough success, Agron began working in film more, first starring in the popular YA adaptation I Am Number Four (2011) as Sarah Hart before taking on films aimed at more diverse audiences, including the 2013 mob-comedy The Family and 2015's Bare, in which she portrays a sheltered young woman who becomes influenced by a drifter. She made her professional theatrical debut on the West End in 2015, as well as branching out into direction by working on several music videos. In 2017, Agron began performing as a singer at the Café Carlyle in New York City, while continuing to star in successful films including Novitiate in 2017 and Shiva Baby in 2020. She also directed part of the poorly-received 2019 anthology feature film Berlin, I Love You, as well as acting in it. Agron is Jewish and has spoken to how her religion relates to her career. Besides performing and directing, she has been involved with significant charity work, particularly in support of LGBT+ rights and human rights.
