Susianna "Susi" Levonovna Kentikian (Armenian: Սյուզի Կենտիկյան; born Syuzanna Kentikyan on 11 September 1987) is an Armenian-German professional boxer. She was born in Yerevan, Armenian SSR, but left the country with her family at the age of five because of the Nagorno-Karabakh War. Kentikian has lived in Hamburg since 1996 and began boxing at the age of twelve. Following a successful amateur career, she turned professional in 2005 upon signing with the Hamburg-based Spotlight Boxing promotion.
Kentikian is a two-time flyweight world champion, having held the World Boxing Association (WBA) female title from 2007 to 2012, and from 2013 to 2017. Additionally, she was the World Boxing Organization (WBO) flyweight champion from 2009 to 2012, and held the Women's International Boxing Federation (WIBF) title from 2007 to 2012 and 2015 to 2017.
Until 2012, Kentikian remained undefeated as a professional, winning 16 of her first 30 fights by knockout or stoppage. The German television station ZDF has broadcast her fights since July 2009. She had previously headlined fight cards for the television station ProSieben from 2007 to 2009. Kentikian has gained minor celebrity status in Germany and she hopes to reach a popularity similar to that of the retired German female boxing star Regina Halmich.
