Seyran Ateş (born 20 April 1963) is a German lawyer and Muslim feminist born in Istanbul, Turkey of Kurdish descent. Her family moved to Germany when she was six years old. She studied law at the Free University of Berlin and has practiced law since 1997, specializing in criminal law and family law. Ateş, a renowned civil-rights activist, is best known for demanding equal rights for Muslim women and girls.

Her views, highly critical of an immigrant Muslim society that is often more conservative than its counterpart in Turkey, have put her at risk. Her German language book Islam needs a sexual revolution was scheduled for publication in Germany in 2009. In an interview in January 2008 on National Public Radio, Ateş stated that she was in hiding and would not be working on Muslim women's behalf publicly (including in court) due to the threats against her. In one particular incident, she and her client were attacked by a woman's husband in a German courthouse in front of onlookers who did nothing.

Ms Ates opened the Ibn Ruschd-Goethe mosque in 2017. It's the first liberal mosque in Germany where men and women pray together and women can take the role of imam leading a prayer. The Turkish religious authority and the Egyptian Fatwa Council at the Al-Azhar University have condemned her project and she has received death threats. The fatwa encompassed all present and future liberal mosques.
