Boyanka Kostova (Bulgarian: Боянка Костова) (born 10 May 1993) is a Bulgarian naturalized Azerbaijani weightlifter. She competed at the 2012 Summer Olympics in the women's 58 kg, finishing in fifth place.
In June 2016, following the Russian doping scandal, it was announced by IWF that retests of the samples taken from the 2012 Olympics indicated that Kostova had tested positive for prohibited substances, namely Dehydrochloromethyltestosterone and Stanozolol. If confirmed, she faces losing all results and medals earned from the date of the sample in 2012 to 2016. In November 2016 the IOC Disciplinary Commission disqualified Kostova from the 2012 Olympic Games.
