Mahin Qadiri (Persian: مهین قدیری) (1977 – December 20, 2010) was an Iranian serial killer who was convicted of robbing and killing six elderly people (one man in 2006, and five women between February and May 2009) in Qazvin. She was subsequently convicted, sentenced to death and promptly hanged in 2010. Qadiri holds the distinction of being the country's first identified, and thus far only confirmed, female serial killer.
