Mavie Hörbiger (born November 14, 1979 in Munich) is a German-Austrian actress. She has both German and Austrian citizenship. Actress Christiane Hörbiger is her aunt, comedian Christian Tramitz is a first cousin.

She did not complete college but visited the acting school of Christa Willschrei in Munich. In 1996, she made her on-camera debut in Michael Gutmann's television feature "Nur für eine Nacht".

Mavie had theatre engagements in Hanover and Bochum (Rachel in Sanft und grausam, 2006; Jeannie in Fettes Schwein, 2005; title role in Lulu, 2004; Gilda in Komödie der Verführung, 2002; Santuzza in Freunde II, 2001). From 2006 to 2008 she performs at the Theater Basel, her first role there being "Roxane" in the play Cyrano de Bergerac, followed by "Stella" in A Streetcar Named Desire.

In 2004, she ranked third in the voting for the 100 Sexiest Women In The World held by the German edition of FHM magazine, just behind Britney Spears and Heidi Klum. Although Mavie has already ranked in the top 100 five times (in 2002, 2004, 2005. 2006 and 2008) and is widely believed to be one of the most attractive German women, she has turned down offers to pose nude for the German edition of Playboy magazine.
